I'm getting below message in output while running flutter pub get even though I've downgraded google map package to google_maps_flutter: ^0.5.33 which is <1.0.0.
[proj_name] flutter pub get
Running "flutter pub get" in proj_name...                    
The current Flutter SDK version is 1.22.0-9.0.pre.
Because proj_name depends on google_maps_flutter >=1.0.0 which requires Flutter SDK version >=1.22.0 <2.0.0, version solving failed.
pub get failed (1; Because proj_name depends on google_maps_flutter >=1.0.0 which requires Flutter SDK version >=1.22.0 <2.0.0, version solving failed.)
exit code 1

environment:
  sdk: ">=2.7.0 <3.0.0"

  flutter:
    sdk: flutter

Result of flutter --version
Flutter 1.22.0-9.0.pre • channel unknown • unknown source
Framework • revision 7a43175198 (3 months ago) • 2020-08-28 23:18:04 -0400
Engine • revision 07e2520d5d
Tools • Dart 2.10.0 (build 2.10.0-73.0.dev)
                Follow up the steps:
flutter channel stable
flutter upgrade
Then Try again if you get the same error then
just change in your pubspec.yaml file: from this
google_maps_flutter: ^0.5.33
to this
google_maps_flutter: 
It will automatically work as it will find out the version which is compatible itself.
