[2025-08-19 10:15] - Firefly III Transaction Submission API Research

Researched Firefly III API documentation for submitting transactions.
Found the correct endpoint: POST /api/v1/transactions.
Identified required and optional JSON fields for a transaction.
Obtained an example curl command for submitting a transaction.

Key Information:

Endpoint: POST /api/v1/transactions
Required Headers:
- Authorization: Bearer YOUR_ACCESS_TOKEN
- Content-Type: application/json

Example JSON Payload:

{
  "transactions": [
    {
      "type": "withdrawal",
      "date": "2023-10-01",
      "amount": "100.00",
      "description": "Groceries",
      "source_id": 1,
      "destination_id": 2,
      "category_id": 3,
      "budget_id": 4
    }
  ]
}

Example curl Command:

curl -X POST "https://your-firefly-iii-instance.com/api/v1/transactions" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
  "transactions": [
    {
      "type": "withdrawal",
      "date": "2023-10-01",
      "amount": "100.00",
      "description": "Groceries",
      "source_id": 1,
      "destination_id": 2,
      "category_id": 3,
      "budget_id": 4
    }
  ]
}'

(Note: Replace YOUR_ACCESS_TOKEN and the instance URL with actual values)

[2025-08-19 10:30] - Firefly III Accounts Retrieval API Research

Researched Firefly III API documentation for retrieving accounts.
Found the correct endpoint: GET /api/v1/accounts.
Learned how to filter accounts by type (e.g., asset, expense, revenue).
Obtained example curl commands for fetching accounts.

Key Information:

Endpoint: GET /api/v1/accounts
Required Headers:
- Authorization: Bearer YOUR_ACCESS_TOKEN
- Accept: application/json
Query Parameters:
- type: Filter accounts by type (asset, expense, revenue, liability, loan, debt, mortgage).
- page: For pagination.

Example curl Commands:

# Get all accounts
curl -X GET "https://your-firefly-iii-instance.com/api/v1/accounts" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Accept: application/json"

# Get only 'asset' accounts (commonly used as source accounts)
curl -X GET "https://your-firefly-iii-instance.com/api/v1/accounts?type=asset" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Accept: application/json"

# Get 'expense' accounts (commonly used as destination for withdrawals)
curl -X GET "https://your-firefly-iii-instance.com/api/v1/accounts?type=expense" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Accept: application/json"

Response Structure: The response includes a data array where each account object has an id and attributes containing details like name and type.

[2025-08-19 10:45] - Create `curl_scripts` Directory and Scripts

Created a new directory curl_scripts to store our API interaction scripts.
Created get_accounts.sh:
- Script to fetch accounts from Firefly III using GET /api/v1/accounts.
- Includes examples for fetching all accounts, 'asset' accounts (source), and 'expense' accounts (destination).
- Uses environment variables for URL and token for security.
Created submit_dummy_transaction.sh:
- Script to submit a dummy transaction to Firefly III using POST /api/v1/transactions.
- Uses environment variables for URL, token, source ID, and destination ID.
- Includes basic error handling and response code checking.
Made both scripts executable with chmod +x.

[2025-08-19 11:00] - Update `get_accounts.sh` Script for Filtering

Updated curl_scripts/get_accounts.sh to accept an optional ACCOUNT_TYPE environment variable.
This allows fetching specific types of accounts (e.g., asset, expense) to reduce output clutter.

Example usage:

YOUR_FIREFLY_III_URL="..." YOUR_ACCESS_TOKEN="..." ACCOUNT_TYPE="asset" ./curl_scripts/get_accounts.sh

Added debug output to show the final URL being used by the script.
Re-applied executable permissions to the updated script.

[2025-08-19 11:15] - Clarify Account Types for 'Receipt' Context

Discussed the specific account types needed for submitting a 'receipt' (struk) transaction.
For a 'receipt' representing incoming funds/purchase:
- source_id: Should be an account of type revenue (e.g., Salary, Gift). This is where the money is considered to come from.
- destination_id: Should be an account of type asset (e.g., Checking Account, Cash Wallet). This is where the money ends up.
Updated understanding for using get_accounts.sh:
- Run once with ACCOUNT_TYPE="revenue" to find a suitable source_id.
- Run once with ACCOUNT_TYPE="asset" to find a suitable destination_id.
These IDs will then be used with submit_dummy_transaction.sh to create the transaction record in Firefly III.

[2025-08-19 11:30] - Fix Bug in `submit_dummy_transaction.sh`

Identified and fixed a bug in curl_scripts/submit_dummy_transaction.sh that caused error line 25: Dummy: command not found.
The issue was due to an incorrect use of a multiline string variable assignment (read -r -d '' ... << EOM).
The script was updated to build the JSON payload directly within the curl command using -d with proper escaping. This is a more robust and portable method.
Re-applied executable permissions to the corrected script.

[2025-08-19 11:45] - Fix Account Type Mismatch & Add Transaction Type Flexibility

Diagnosed the HTTP Code: 000 and subsequent Firefly III error [a] Could not find a valid source account....
Root cause: The transaction type in submit_dummy_transaction.sh was hardcoded to withdrawal, which is incompatible with using a revenue account as source_id.
Solution Implemented:
- Updated curl_scripts/submit_dummy_transaction.sh to accept an optional TRANSACTION_TYPE environment variable.
- Default value for TRANSACTION_TYPE is now set to deposit, which is the correct type when source_id is revenue and destination_id is asset.
- Example usage for 'receipt' context:
```
YOUR_FIREFLY_III_URL="..." YOUR_ACCESS_TOKEN="..." SOURCE_ACCOUNT_ID=92 DESTINATION_ACCOUNT_ID=1 TRANSACTION_TYPE="deposit" ./curl_scripts/submit_dummy_transaction.sh
```
This change provides more flexibility for testing different transaction types and ensures compatibility with the intended account types for a 'receipt'.
Re-applied executable permissions to the updated script.

[2025-08-19 12:00] - Successfully Submit Dummy Transaction via `curl`

After correcting the account types and transaction type, successfully submitted a dummy transaction using submit_dummy_transaction.sh.
Confirmed that source_id from a revenue account and destination_id from an asset account, with TRANSACTION_TYPE="deposit", works correctly.

[2025-08-19 12:15] - Start Integrating with Flutter App

Goal: Create a Flutter screen to select source and destination accounts from Firefly III and submit a transaction.
Checked pubspec.yaml and confirmed http: ^1.5.0 is already included.
Created lib/models/firefly_account.dart:
- Defined a FireflyAccount model to represent account data from the API.
- Includes id, name, and type properties.
- Has a fromJson factory constructor for easy parsing.
Created lib/services/firefly_api_service.dart:
- Defined FireflyApiService class to encapsulate API calls.
- Includes fetchAccounts({String? type}) to get accounts, filtering by type if provided.
- Includes submitDummyTransaction to send a transaction to the API.
- Uses Bearer token authentication.
Created lib/screens/transaction_screen.dart:
- Defined TransactionScreen widget.
- Fetches revenue and asset accounts on initialization.
- Displays two dropdowns for selecting source (revenue) and destination (asset) accounts.
- Includes buttons to reload accounts and submit a dummy transaction.
- Shows loading indicators and status messages.

[2025-08-19 12:30] - Improve Security & User Experience

Recognized that hardcoding URL/token is insecure. Implemented a better approach.
Created lib/screens/config_screen.dart:
- New screen for users to input Firefly III URL and Personal Access Token.
- Uses TextField for input with basic validation.
- Stores credentials securely using shared_preferences.
Modified lib/services/firefly_api_service.dart:
- Removed hardcoded URL and token.
- Updated fetchAccounts and submitDummyTransaction methods to accept baseUrl and accessToken as required parameters.
Modified lib/screens/transaction_screen.dart:
- Updated to load URL and token from shared_preferences.
- Passes loaded credentials to FireflyApiService methods.
- Adds a settings icon in the app bar to navigate to ConfigScreen.
- Handles cases where credentials are missing or invalid.

[2025-08-19 13:00] - Add Debug Logging for Account Loading

Added extensive debug print statements to FireflyApiService and TransactionScreen.
Purpose: To trace the flow of data loading, identify where the process might be failing, and verify if accounts are successfully fetched and parsed from the Firefly III API.
This will help diagnose why the dropdowns for source and destination accounts might appear empty even after configuration is set.

[2025-08-20 14:00] - Refactor main.dart and Correct Transaction Payload

Corrected the payload in lib/services/firefly_api_service.dart's submitDummyTransaction method. Ensured that source_id and destination_id are passed as strings to align with Firefly III API expectations.
Refactored lib/main.dart to improve the initial application flow.
Set TransactionScreen as the initial route (/).
Added named routes for TransactionScreen (/), ConfigScreen (/config), and ReceiptScreen (/receipt) to create a clear and maintainable navigation structure.
This change directs the user to the primary transaction interface on startup, facilitating immediate testing of the core functionality being developed.

[2025-08-20 14:30] - Fix Compilation and Runtime Errors

Resolved build errors caused by incorrect import paths and class names in lib/screens/receipt_screen.dart and lib/screens/settings_screen.dart.
Corrected the import from firefly_service.dart to firefly_api_service.dart.
Renamed all instances of FireflyService to the correct class name, FireflyApiService.
Implemented the missing testConnection and testAuthentication methods in lib/services/firefly_api_service.dart to enable configuration testing.
Updated lib/screens/settings_screen.dart to pass the required baseUrl and accessToken parameters to the new API service methods.
The application is now in a runnable state, allowing for further testing of the Firefly III integration.

[2025-08-20 15:00] - Redesign Receipt UI to Match Sample Image

Redesigned the ReceiptScreen UI to match a more traditional receipt format similar to sample-struk.jpg.

The UI now has a more professional receipt appearance with proper spacing, dividers, and formatting.

[2025-08-20 16:00] - Update Receipt UI with Courier Font and Fix Layout Issues

Added google_fonts dependency to pubspec.yaml to use Courier Prime font for a more authentic receipt appearance.
Updated ReceiptScreen to use a fixed-width layout that resembles a physical receipt.
Added transaction details like cashier ID and transaction ID.
Improved the overall styling with better spacing, dividers, and a thank you message.
Fixed syntax errors in the receipt_screen.dart file that were preventing the app from building correctly.
Successfully ran the app on a physical device and verified that the new UI is displayed correctly.
Confirmed that the app can be navigated to the ReceiptScreen, though it currently defaults to TransactionScreen as the home route.

[2025-08-20 17:00] - Fix PDF Export Path and Add PDF Opening Functionality

Updated PdfExportService to use the application documents directory instead of temporary directory for saving PDF files.
Added a function to open the generated PDF file using the open_file package.
Modified _printReceipt function in ReceiptScreen to automatically open the generated PDF after creation.
This ensures that users can easily access and view the generated receipt PDFs on their devices.

[2025-08-20 18:00] - Implement Bluetooth Thermal Printer Functionality

Integrated the bluetooth_print plugin to enable printing receipts on thermal printers.
Added Bluetooth device scanning and connection functionality in ReceiptScreen.
Implemented a function to format and print receipts to thermal printers using the ESC/POS protocol.
Added UI elements to connect to Bluetooth printers and print receipts.
The thermal printer functionality allows users to print receipts directly from the app to compatible Bluetooth thermal printers.

[2025-08-20 19:00] - Fix UI Overflow and setState() After Dispose Errors

Fixed UI overflow error in ReceiptScreen by properly sizing the action buttons using Expanded widgets.
Resolved setState() called after dispose errors in SettingsScreen by adding mounted checks before calling setState().
These fixes improve the stability and user experience of the application.
