Build failed on SchedulerBinding.instance.addPostFrameCallback((_)

[spokV]

Hi
Just cloned the latest master and perform build on linux machine (fedora 35) using sdk 2.10.1, and I get the following result:

lib/feature_discovery/feature_discovery.dart:224:35: Error: Method 'addPostFrameCallback' cannot be called on 'SchedulerBinding?'
because it is potentially null.
'SchedulerBinding' is from 'package:flutter/src/scheduler/binding.dart'
('../flutter/packages/flutter/lib/src/scheduler/binding.dart').
Try calling using ?. instead.
SchedulerBinding.instance.addPostFrameCallback(() {
^^^^^^^^^^^^^^^^^^^^
lib/feature_discovery/feature_discovery.dart:240:37: Error: Method 'addPostFrameCallback' cannot be called on 'SchedulerBinding?'

Try calling using ?. instead.
SchedulerBinding.instance.addPostFrameCallback(() {
^^^^^^^^^^^^^^^^^^^^
Target kernel_snapshot failed: Exception
Failed to build bundle.

I can fix the issue by apply the suggested fix in build output text but was thinking if it can cause other issues on run time..

Best Regards

Hi,
Thanks for filing issue.
Gallery is currently configured to build against the master channel of flutter.

Discussion regarding making it run with beta/stable is ongoing here.
