[!] 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

Step1

In app/build.gradlem, add the following config.

defaultConfig {

…..

multiDexEnabled true
}
