Hot reload cannot recover from sliver error #133532

mattermoran · 2023-08-29T07:16:21Z

Is there an existing issue for this?

I have searched the existing issues
I have read the guide to filing a bug

Steps to reproduce

Add CustomScrollView
Add a child that not a sliver e.g Container
Save and hot reload
Wrap that container into SliverToBoxAdapter

Expected results

The error disappears and can continue coding as usual

Actual results

The error keeps saying Failed assertion: line 6426 pos 12: 'child == _child': is not true. and does not go away until hot restart.

Code sample

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Sliver error'),
        ),
        body: CustomScrollView(
          slivers: [
            Container(),
          ],
        ),
      ),
    );
  }
}

Thanks for the report @mattermoran

Add CustomScrollView

Add a child that not a sliver e.g Container

This may not be an ideal implementation, ie, to have a non-sliver widget inside a sliver widget. If you are using CustomScrollView which is a sliver widget in itself, it also expects slivers as it takes slivers as children.

If in your case, you used a non-sliver, ie, Container, then it order for this widget structure / implementation to work, you'll need to use SliverToBoxAdapter as you mentioned, as, per its documentation:

Slivers are special-purpose widgets that can be combined using a CustomScrollView to create custom scroll effects, ie, if you are using a non-sliver widget inside a sliver, in order for it to work properly and it helps to allow adding of non-sliver widgets inside the CustomScrollView widget and that's why adding this sliver gets rid of the error as you mentioned.

So the solution you mentioned, to wrap non-sliver with SliverToBoxAdapter is correct.

mattermoran · 2023-08-29T10:54:53Z

Hey @darshankawar
I think you misunderstood what I mean here, let me explain :)

The issue is not that RenderBox is not allowed in a place of slivers but the fact that changing it back to sliver does not go back to a working state after hot reload and only hot restart helps which restarts the whole thing.
I'm working a lot with CustomScrollViews and once in a while I accidentally forget to wrap RenderBox into SliverToBoxAdapter which means now I have to restart the whole thing and it's especially annoying when the page is many levels deep in the routing.

Basically what I'm saying is that I would the error to go away after fixing the mistake without having to restart the app.

darshankawar · 2023-08-30T05:47:17Z

Thanks for the feedback. I do see the same reported behavior using latest stable and master versions.
Running the code as-is throws below error:

======== Exception caught by widgets library =======================================================
The following assertion was thrown building Container:
A RenderViewport expected a child of type RenderSliver but received a child of type RenderLimitedBox.

Upon wrapping Container with SliverToBoxAdapter and then hot reloading throws below error:

======== Exception caught by widgets library =======================================================
The following assertion was thrown building RawGestureDetector-[LabeledGlobalKey<RawGestureDetectorState>#47d5a](state: RawGestureDetectorState#eb2ec(gestures: <none>, behavior: opaque)):
'package:flutter/src/widgets/framework.dart': Failed assertion: line 6627 pos 12: 'child == _child': is not true.

Whereas, the expected behavior per OP is hot reload shouldn't throw above error and currently need to hot restart the app.

Maybe related ? #94416

cc'ing team-tool, not sure if we can gracefully recover this case through hot reload.

cc'ing team-tool, not sure if we can gracefully recover this case through hot reload.

@Piinks is the assertion happening after the hot reload, on the second build?

Piinks · 2023-09-11T21:23:45Z

Yeah. So on the first build it throws because the child is the wrong type, and then changing the child to the right type and hot reloading is where is fails to recover.
