2.1.1 incompatible with flutter_driver

[pdtoal]

Whilst trying to use the latest screenshots flutter plugin, I get:

**Because screenshots >=1.0.0 depends on process ^3.0.9 and every version of flutter_driver from sdk depends on process 4.0.0-nullsafety.4, screenshots >=1.0.0 is incompatible with flutter_driver from sdk.

So, because rootless_practice_app depends on both flutter_driver any from sdk and screenshots ^2.1.1, version solving failed.
pub get failed (1; So, because rootless_practice_app depends on both flutter_driver any from sdk and screenshots ^2.1.1, version solving failed.)**

My dependencies in pubspec.yaml are:

dependencies:
flutter:
sdk: flutter
charcode: ^1.1.2
flutter_midi: ^1.0.1
shared_preferences: ^0.5.6+1
flutter_device_type: ^0.2.0
device_preview: ^0.2.6
auto_size_text: ^2.1.0
#firebase_admob: ^0.9.1+1
intl: ^0.16.1
wakelock: ^0.2.1+1
cupertino_icons: ^0.1.2

dev_dependencies:
flutter_driver:
sdk: flutter
test: any
flutter_test:
sdk: flutter
screenshots: ^2.1.1

How can I use screenshots with the current version of flutter. I'm on Flutter 1.26.0-13.0.pre.54

Thanks

screenshots does not support Nullsafety yet. Its a WIP: Compatibility with Dart 2.10.
