Compiling the App

Before you embark on building the application, ensure you have a working Flutter SDK setup. Sometimes, it’s comparable to preparing your kitchen before a big cooking project – you need all your utensils and ingredients ready.

Here are the steps to follow:

1. Disable signing on build.gradle or change the keystore to sign the app.
2. Set the required Flutter channel to master by using the following commands:

~$ flutter channel master
~$ flutter upgrade

3. Next, building is simple as this:

~$ flutter pub get
~$ flutter run           # for debug
~$ flutter build apk --flavor dev     # release build with dev flavor

The available flavors are dev, production, and ci.

Generating Locales

After adding or updating the locales, run the following command from the Leaflet root directory to generate and update the required files:

dart bin/locale_gen.dart

Troubleshooting

If you encounter any issues while building your application, consider the following troubleshooting tips:

• Ensure your Flutter SDK is properly configured and updated.
• Check your build.gradle file for any misconfigurations regarding signing.
• Make sure you’re on the right channel by using the Flutter channel command.
• If your app crashes, look for error messages in the console that can guide you to what went wrong.
