URI-based automation

URI-based automation

You can add one or more transactions using flow-mn schema uris.

Check out the supported JSON Schema file in schemas folder.

Currencies are based on the account, so there's no way to specify it at the moment.

Adding single transaction

When adding single transactions, properties must be provided as query params.

{
  "title": "Tous les jours",
  "amount": 42000.00
}

turns into:

flow-mn:///transaction/new?title=Tous+les+jours&amount=42000.00

Adding multiple transactions

When adding multiple transactions, you must provide stringified version of the following as "json" query param.

{
  "t": [
    {
      "title": "Fresh blueberry piece",
      "amount": "13000.00",
      "transactionDate": "2011-12-05",
      "category": "Food",
      "tags": "My fave cafe",
      "accountUuid": "faa6d523-277f-46af-9493-67768e5b48ab",
    },
    {
      "title": "Caffe Mocha ice",
      "amount": "10000.00",
      "transactionDate": "2011-12-05",
      "category": "Drinks"
    }
  ]
}

turns into

flow-mn:///transaction/new?json=%7B%22t%22%3A%5B%7B%22title%22%3A%22Fresh%20blueberry%20piece%22%2C%22amount%22%3A%2213000.00%22%2C%22transactionDate%22%3A%222011-12-05%22%2C%22category%22%3A%22Food%22%7D%2C%7B%22title%22%3A%22Caffe%20Mocha%20ice%22%2C%22amount%22%3A%2210000.00%22%2C%22transactionDate%22%3A%222011-12-05%22%2C%22category%22%3A%22Drinks%22%7D%5D%7D

Development

Please read Contribuition guide, and Code of Conduct before contributing.

Prerequisites

Flutter (latest stable)

Other:

JDK 11 or later if you're gonna build for Android
XCode if you're gonna build for iOS/macOS
To run tests on your machine, see Testing

Building for Windows, macOS, and Linux-based systems requires the same dependencies as Flutter. Read more on https://docs.flutter.dev/platform-integration

Testing

If you plan to run tests on your machine, ensure you've installed ObjectBox dynamic libraries.

Install ObjectBox dynamic libraries[^3]:

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-dart/main/install.sh)

Run tests with: flutter test

Support Flow

Flow is a personal project developed during my free time, and it generates no income. Consider helping Flow! Here are some suggestions:

Give a star on GitHub
Leave a review on Google Play and App Store
Tell a friend
Buy me a coffee https://img.buymeacoffee.com/button-api/?text=Buy%20me%20a%20coffee&emoji=%E2%98%95&slug=sadespresso&button_colour=BD5FFF&font_colour=ffffff&font_family=Lato&outline_colour=000000&coffee_colour=FFDD00

Maintaining Flow on the App Store requires a substantial annual fee (see Apple Developer Program), which I currently cover. To ensure Flow's continued existence and future development, your support is greatly appreciated.

Thank you to all the contributors, supporters, testers, and those who contributed indirectly 🤍
