Question

I have a Flutter App that is working totally fine when installed in Debug Mode via Android Studio and Crashing after Login when in Release Mode. I have the Crash Report taken from Play Console:

My pubsec.yaml dependencies are:

version: 1.0.0+3

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  shared_preferences: ^0.4.3
  connectivity: ^0.4.3+1
  firebase_auth: ^0.11.1+6
  geolocator: ^5.0.1
  cloud_firestore: ^0.12.11
  flutter_blue: 0.6.2

  flutter_datetime_picker: ^1.2.4
  permission_handler: ^3.1.0

dev_dependencies:
  flutter_test:
    sdk: flutter

  font_awesome_flutter: ^8.0.1

I tried updating the cloud_firestore plugin but since I am on the stable channel I cannot upgrade to version 0.13.0+1 since minimum Flutter version required is 1.10.0 and I am on version

Flutter 1.9.1+hotfix.6 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 68587a0916 (3 months ago) • 2019-09-13 19:46:58 -0700
Engine • revision b863200c37
Tools • Dart 2.5.0

Also, cloud_firestore 0.13.0 gives the following error:

Invalid argument(s): Minimum version ("0.13.0") must be less than maximum ("0.13.0-0").

This is an unexpected error. Please run


    pub --trace '--verbosity=warning' get --no-precompile




and include the logs in an issue on https://github.com/dart-lang/pub/issues/new
pub get failed (1)

Answer 1

You can use flutter build apk --no-shrink . It will work. But the recommended method would be to update your flutter sdk and also the dependencies you are using in your pubspec.yaml file.

Answer 2

Solve this by

flutter build apk --no-shrink

Answer 3

So I solved it by changing to Flutter Master Channel and upgrading to:

Flutter 1.13.1-pre.94 • channel master • https://github.com/flutter/flutter.git
Framework • revision 36e599eb5d (2 days ago) • 2019-12-11 07:27:13 +0100
Engine • revision 12bf95fd49
Tools • Dart 2.7.0 (build 2.7.0-dev.2.1 8b8894648f)

Also, I upgraded the Cloud Firestore to the latest version since I figured out that this was the plugin that was causing the crash.

I then had to upgrade the dependencies from Android > Build.gradle to :

classpath 'com.android.tools.build:gradle:3.3.1'

Also, I upgraded all the plugins in pubsec.yaml to their latest versions and fixed all the breaking changes.

After this, flutter clean and then flutter build apk and everything worked fine.

Answer 4

Try to run flutter pub cache repair at command line and sync your gradle files from Android Studio.

You could take Android X error after that. Simply could migrate to Android X if you takes
