You can get both by

dependencies:
  meta: ^1.2.2

dependency_overrides:
  meta: ^1.1.8
user_67464750

Do this,

meta: ^1.1.8

And then, run this,

flutter pub get

hi there try to downgrade the version of meta to 1.1.8 i tried and it worked with me in flutter 1.20.1

I experienced a similar issue with Firebase auth and permission_handler:

# pubspec.yaml: 
dependencies:
  flutter:
    sdk: flutter
  firebase_auth: ^1.4.1
  permission_handler: ^5.1.0+2

The error message (truncated):

Because permission_handler ^5.1.0 depends on permission_handler_platform_interface ^2.0.2 which depends on plugin_platform_interface ^1.0.2, permission_handler ^5.1.0 requires plugin_platform_interface ^1.0.2.
And because firebase_auth 1.4.1 depends on firebase_core_platform_interface ^4.0.1 and no versions of firebase_auth match >1.4.1 <2.0.0, permission_handler ^5.1.0 is incompatible with firebase_auth ^1.4.1.
So, because my_flutter_project depends on both firebase_auth ^1.4.1 and permission_handler ^5.1.0+2, version solving failed.

A solution that worked for me: Update permission_handler to the latest version:

flutter pub add permission_handler

I have same problem with bloc:

Because every version of passcode_navigator from git depends on flutter_bloc ^7.3.3 and every version of feature_menu from path depends on flutter_bloc ^8.0.0, passcode_navigator from git is incompatible with feature_menu from path

I resolve it with adding to pubspec:

dependency_overrides:
  flutter_bloc: any

Update meta to 1.2.2

meta: ^1.2.2

also update flutter using flutter upgrade command

flutter upgrade
