Flutter Cloud Firestore Plugin Issue on Android

[dmilicic]

Steps to Reproduce

I can't build my Flutter app with the Cloud Firestore plugin for Android!

I followed the example here: https://www.youtube.com/watch?v=DqJ_KjFzL9I

This is a sample app that can not build for Android: https://github.com/dmilicic/flutter-firestore-issue

Pretty much the same issue as here but could not get it resolved by any means: #27128

I tried all kinds of version variations of dependencies with no positive result. The sample app has the Cloud Firestore plugin at version 0.9.0 which should the be latest at this time.

NOTE: It works fine for iOS.

Sample app's pubspec.yaml

name: flutter_firestore_issue
description: A new Flutter application.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.
version: 1.0.0+1

environment:
  sdk: ">=2.0.0-dev.68.0 <3.0.0"

dependencies:

  cloud_firestore: 0.9.0

  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.io/custom-fonts/#from-packages

This issue is caused by the migration of the plugins to AndroidX. This comment explains what caused it and how you can resolve the issue: #27106 (comment)

So doing a Refactor > Migrate to AndroidX did nothing so I manually migrated all of my build.gradle dependencies as described here: https://developer.android.com/jetpack/androidx/migrate

This made it work!

This doesn't sound Flutter related, or is it?

I think this is because if a Flutter project is opened at its root directory in Android Studio, the IDE doesn't actually pick up on any of the Android code enough to provide automated refactoring or edit gradle files. For the automatic refactoring to work the android subdirectory specifically needs to get imported as an Android app. I briefly mentioned it in that comment but didn't really explain the problem. Edited the comment with more information. I'm also working on a PR that will log a warning to the console when these plugins are pulled into gradle and will add instructions for this: flutter/plugins#1138.
