[bug?] add rendering.dart on tab_button_widget.dart to fix SystemMouseCursors.click error

[b14cknc0d3]

i need to add this for window[tested] to fix MouseRegion in src\tabbed_button_widget.dart import 'package:flutter/rendering.dart';

return MouseRegion(
        cursor: SystemMouseCursors.click,
        onEnter: _onEnter,
        onExit: _onExit,
        child: GestureDetector(child: icon, onTap: onPressed));
  }

This is scary as it compiles normally without the import. Did you have a problem with Windows? What is the problem? The cursor does not change? It only worked when you added the import?

When I was using tabbed view first time . I was facing the same problem and I commented out

 SystemMouseCursors 

somewhere I don't remember the exact location. Today when I updated to the latest package. Then the problem also occurred. So, I imported the import 'package:flutter/rendering.dart'; base on the StackOverflow question, and it worked fine.

Hi!

Do you still have the link to this question on StackOverflow? If so, I can link to the issue.

Are you locally changing a clone of tabbed_view by adding this import and then importing that changed tabbed_view into your project?

statckoverflow No, I change directly to the package [pub-cache] Here is the Logs. If I don't add rendering. dart it won't build.

OK! I'm finalizing another bug then I generate a version with both.

If possible, can I ask you a favor? This looks like a bug in Flutter! Could you open an issue for them? It's easy, just paste this build text, a sample code, and the result of "flutter doctor -v". With that, I will be able to commit with a comment with this import linking to this issue. Otherwise, in the future, this import may be unintentionally removed.

As I don't have Windows, the result of the "flutter doctor -v" will be different.

Sample code:

import 'package:flutter/material.dart';
// Build with error without this import:
import 'package:flutter/rendering.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Center(
      child: MouseRegion(
          cursor: SystemMouseCursors.click,
          onEnter: (event) => print("onEnter"),
          onExit: (event) => print("onExit"),
          child: Container(width: 50, height: 50, color: Colors.blue)),
    ));
  }
}

@b14cknc0d3 , they closed the issue. Apparently, you just need to update the Flutter version. I'll close this issue as well, ok?

[b14cknc0d3]
