in pubsec added extended_text_field: 0.4.9
flutter version: Flutter - Channel master, v1.18.0-10.0.pre, Microsoft Windows [Version 10.0.18362.778]

[zmtzawqlp]

any error in stable 1.17.0?

[pratheeshrussell]

any error in stable 1.17.0?

No error in stable.

[venliong]

I'm using 1.17.1 beta.

open <flutterSDK>/.pub-cache/hosted/pub.flutter-io.cn/extended_text_field-0.5.0/lib/src/extended_editable_text.dart and add the missing implementations :

@override AutofillScope get currentAutofillScope => null;

@override
showAutocorrectionPromptRect(int start,int end){

 }

[Wing-Li]

There are still problems, it can't be used at all

[zmtzawqlp]

we focus on Flutter Stable Branch , api changes frequently in beta/dev/master

[ismilesky]

how to solve ? change stable channel? @zmtzawqlp

[zmtzawqlp]

how to solve ? change stable channel? @zmtzawqlp

yes, or you can fork it and change it at your side

[johngithubby]

It also fails for Flutter 1.20, package ver 3.0.1
