Null Safety Error

Apparently, this package isn't fully null safety compliant

/C:/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_typeahead-4.0.0/lib/src/flutter_typeahead.dart:803:29: Error: Method 'addPostFrameCallback' cannot be called on 'WidgetsBinding?' because it is potentially null.

  • 'WidgetsBinding' is from 'package:flutter/src/widgets/binding.dart' ('/C:/flutter/packages/flutter/lib/src/widgets/binding.dart'). package:flutter/…/widgets/binding.dart:1 Try calling using ?. instead. WidgetsBinding.instance.addPostFrameCallback((duration) {

Use the previous version3.2.7. It worked for me.

Yes the major version change is for the new flutter and the older version is for the old flutter -- and type safety .. The WAY WAY older version is for non-type safety and will not longer be maintained ..

So make your app null-safe and Flutter 3 compatible and use Typeahead V4 .. that's the only version going forward that will be maintained ..
