BUILD FAILED in 41s
[!] App requires Multidex support
    Multidex support is required for your android app to build since the number of methods has exceeded 64k. See https://docs.flutter.dev/deployment/android#enabling-multidex-support for more information. You may pass the --no-multidex flag to skip Flutter's multidex support to use a manual solution.

    Flutter tool can add multidex support. The following file will be added by flutter:

        android/app/src/main/java/io/flutter/app/FlutterMultiDexApplication.java

cannot prompt without a terminal ui
Exception: Gradle task assembleDebug failed with exit code 1

    You need to enable MultiDex as mentioned in your errorcode. You can do it in your "build.gradle". Usually this failure code appears if your files are getting larger or you use a lot of assets.

    Guide on how to do it.

    In your stack trace you can see additional Infos on how to enable it.
