I'm facing this issue when running some flutter unit test that calls some code that uses getApplicationDocumentsDirectory():

package:flutter/src/services/platform_channel.dart 368:7  MethodChannel._invokeMethod

MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider)

This was running a few weeks ago, so it seemengly got broken after some flutter/deps upgrade.

These are the deps in my pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  flame: ^1.22.0
  flame_audio: ^2.10.3
  flame_fe2d: ^0.18.2
  shared_preferences: ^2.0.13
  package_info_plus: ^8.1.0
  sprintf: ^6.0.0
  archive: ^3.3.4
  path_provider: ^2.0.15
  sqflite: ^2.4.0
  cupertino_icons: ^1.0.8
  crypto: ^3.0.6
  path: ^1.9.0
  intl: ^0.20.1
  logging: ^1.3.0

And this is my flutter doctor output:

 % flutter doctor

I have seen several other questions related to this in StackOverflow but none specifically addressing the case of unit tests running on Mac, and none of the advice on these others helped me to fix this specific issue.

There's no getApplicationDocumentsDirectory implementation on the test environment. So you should set a mock handler using setMockMethodCallHandler.
This answer might be helpful.
