Facing issue with new Flutter upgrade.

This is not letting me build the project.

• 'SchedulerBinding' is from 'package:flutter/src/scheduler/binding.dart' ('/D:/Development/SDK/Flutter/flutter/packages/flutter/lib/src/scheduler/binding.dart'). Try calling using ?. instead.

Hi @praveengupta0895 ,

We suspect that you haven't upgraded your Flutter SDK to the latest version. Our chart package is compatible with Flutter latest version, so we request to upgrade your Flutter SDK to resolve the mentioned issue.

Thanks, Dharani.
