Hi Ken,

just wanna thank you, this project is amazing

I just wanna share my problem with this project

I got this error

Exception: Gradle build failed to produce an .apk file. It's likely that this file was generated under
/home/myusername/Git/create_flutter_provider_app/build, but the tool couldn't find it.

And i do solve it with creating new flutter project then copy build.grade in app folder, and paste it to your amazing template

I had the same error. For me it was because I clicked the default run main.dart button to start the app.
I adjusted the run configuration for "dev" and "prod" as described in "Extras 2: Config Android Studio to run Flutter Flavor" here https://medium.com/@vo9312/flutter-series-part-1-flutter-flavors-setup-bb6aba1586ac

Hi @FunGuardian , thanks for the sharing. Is the exception occur everytime when you build or occasionally few times? The reason I asked this is because, I encounter before and although the exception was thrown, but the .apk file is successfully build in the project build output folder.

This only occurs when not running the specified commands from the documentation:

flutter run --flavor prod -t lib/main_prod.dart or flutter run --flavor dev -t lib/main.dart

If you are using VS Code, add these on your launch.json -> configurations

        {
            "name": "Dev",
            "request": "launch",
            "type": "dart",
            "args": [
                "--flavor",
                "dev",
                "-t",
                "lib/main.dart"
            ]
        },
        {
            "name": "Prod",
            "request": "launch",
            "type": "dart",
            "args": [
                "--flavor",
                "prod",
                "-t",
                "lib/main_prod.dart"
            ]
        }

Hi @kirkcharlesniv , @rainerlonau ,

Thanks a lot for the comment and helps. This helps a lot.

I will need to update the README on this.

Hello @KenAragorn , if I might make a suggestion, on the README.md step 10

Instead of:

Done. Try launch the app using emulator or your preferred physical test device. For first time user, you need to create a new account from the app.

maybe a more accurate documentation would be:

Done. Try launch the app using emulator or your preferred physical test device by using flutter run --flavor dev -t lib/main.dart. For first time users, you need to create a new account from the app.

I'm only suggesting this because I too got stuck here for a few minutes until I realized what was wrong, and only now found this issue that clarifies the situation.

            "args": [

                "lib/main.dart"
            ]
        },
        {
            "name": "Prod",
            "request": "launch",
            "type": "dart",
            "args": [
                "--flavor",
                "prod",
                "-t",
                "lib/main_prod.dart"
            ]
        }

Also, this configuration worked better for me (file .vscode/launch.json)

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Dev",
            "request": "launch",
            "type": "dart",
            "flutterMode": "debug",
            "program": "lib/main.dart",
            "args": [
                "--flavor",
                "dev"
            ]
        },
        {
            "name": "Prod",
            "request": "launch",
            "type": "dart",
            "flutterMode": "release",
            "program": "lib/main_prod.dart",
            "args": [
                "--flavor",
                "prod"
            ]
        }
    ]
}
