Please help me with it thanks
Because every version of flutter_test from sdk depends on async 2.6.1 and fstore depends on async 2.5.0, flutter_test from sdk is forbidden.
So, because fstore depends on flutter_test any from sdk, version solving failed.
pub finished with exit code 1
My pubspec.yaml
name: fstore
publish_to: "none"

# 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.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
