Error: Method 'addPostFrameCallback' cannot be called on 'SchedulerBinding?' because it is potentially null

Hi

I am building this plugin but do not work anymore because give me this error:


~/flutter/.pub-cache/hosted/pub.dartlang.org/syncfusion_flutter_charts-20.1.58/lib/src/chart/base/chart_base.dart:1820:35: Error: Method 'addPostFrameCallback' cannot be called on 'SchedulerBinding?' because it is potentially null.

 - 'SchedulerBinding' is from 'package:flutter/src/scheduler/binding.dart' ('/C:/Data/flutter/packages/flutter/lib/src/scheduler/binding.dart').

Try calling using ?. instead.

        SchedulerBinding.instance.addPostFrameCallback((_) {

                                  ^^^^^^^^^^^^^^^^^^^^

I need with urgency that updated all plugin of syncfusion with codemagic


Regards,

Cees
