rrousselgit / boundary Goto Github PK

I actually encountered this awhile back, but it slipped my mind to report...but then it popped back in, so here I am. :)

The Stack being used in the boundary is modifying constraints, so when the boundary is applied, a widget will sometimes render differently than it would without.

I encountered this with a situation similar to:

• Stack
  • Positioned.fromRect // tight constraints
    • Boundary // constraints loosened
      • DecoratedBox // sizes to zero

I suspect this isn't desired. If you agree, happy to send a PR.

I'm finding this very useful, btw. We work with widgets that can't be trusted, and boundary is keeping them in line.

Hi Remi,

I know this library is experimental and all that, but would it be possible to add a license?

Thanks :)

Hi,

I see that this project is still experimental, do you have any plan to make a stable version?

If not do you have any idea how you could approach this? I mean overlay is not ideal because you might create a duplicate GlobalKey right?

I saw your discussion with the flutter team about enabling support for boundaries, especially to handle error in the build method. As you mentioned, this is sometimes used as a feature is React and I think I need this for one of my project.

What is the reasoning behind f81146f? Catching exceptions sounded like one of the main points of this project.

Or do I miss something and the following code should still show the fallback widget?

import 'package:boundary/boundary.dart';
import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: const Text('hello')),
        body: Boundary(
          fallbackBuilder: (context, error) {
            return const Center(child: Text('Oops'));
          },
          child: Container(
            color: Colors.red,
            padding: const EdgeInsets.all(50),
            child: Builder(builder: (_) {
              throw 42;
            }),
          ),
        ),
      ),
    );
  }
}
