Padding changes while dragging ` ReorderableListView` on web and desktop #147419

Closed arturoszulc closed 12 hours ago

arturoszulc commented 2 weeks ago

Steps to reproduce

Start dragging any list element (Tested on Chrome Browser)

Expected results

Padding stays intact

Actual results

Padding changes (the whole tile shifts down) To fix this I have to either resign from ListTile or Align widget. But I need both to keep hoverColor and prevent Card from stretching.

Code sample

Code sample ```dart import 'package:flutter/material.dart'; void main() { runApp(const MainApp()); } class MainApp extends StatelessWidget { const MainApp({super.key}); @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( body: ReorderableListView( onReorder: (oldIndex, newIndex) {}, children: const [ ListRow(key: ValueKey('0'), text: '000000'), ListRow(key: ValueKey('1'), text: '111111'), ListRow(key: ValueKey('2'), text: '222222'), ], )), ); } } class ListRow extends StatelessWidget { const ListRow({super.key, required this.text}); final String text; @override Widget build(BuildContext context) { return Padding( padding: const EdgeInsets.all(10.0), child: ListTile( hoverColor: Colors.blue, onTap: () {}, title: Row( children: [ const Expanded( flex: 2, child: Text('HelloWorld'), ), Expanded( flex: 4, child: Align( alignment: Alignment.centerLeft, child: Card( margin: EdgeInsets.zero, child: Padding( padding: const EdgeInsets.all(8.0), child: Text(text), ), ), )) ], ), ), ); } } ```

Thanks for the report @arturoszulc I see below upon running the code sample:

https://github.com/flutter/flutter/assets/67046386/537811c5-11db-44a5-a967-00d95dffdb86

Can you please elaborate when you says padding changes or provide us a short video that shows the behavior ?

arturoszulc commented 2 weeks ago

Steps to reproduce: Start draggin any list element. Upon drag start, right in the moment of mouse click, ListTile contents shift down:

https://github.com/flutter/flutter/assets/61434086/cd95f5bc-b9fa-4fa9-8ba5-858a685f0a99

Instead, it should look like this:

arturoszulc commented 2 weeks ago

Additional side by side comparison. Look how content of a ListTile is shifted down. This makes ListTile unsymmetrical: side by side

darshankawar commented 2 weeks ago

Thanks for the updates. Can you check if your issue resembles https://github.com/flutter/flutter/issues/63527 or not ?

arturoszulc commented 1 week ago

Nope. Differences:

Example without Card widget:

import 'package:flutter/material.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: ReorderableListView(
        onReorder: (oldIndex, newIndex) {},
        children: const [
          ListRow(key: ValueKey('0'), text: '000000'),
          ListRow(key: ValueKey('1'), text: '111111'),
          ListRow(key: ValueKey('2'), text: '222222'),
        ],
      )),
    );
  }
}

class ListRow extends StatelessWidget {
  const ListRow({super.key, required this.text});

  final String text;

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(10.0),
      child: ListTile(
        hoverColor: Colors.blue,
        onTap: () {},
        title: Row(
          children: [
            const Expanded(
              flex: 2,
              child: Text('HelloWorld'),
            ),
            Expanded(
                flex: 4,
                child: Align(
                  alignment: Alignment.centerLeft,
                  child: Container(
                    color: Colors.red,
                    margin: EdgeInsets.zero,
                    child: Padding(
                      padding: const EdgeInsets.all(8.0),
                      child: Text(text),
                    ),
                  ),
                ))
          ],
        ),
      ),
    );
  }
}

I found a workaround to my problem: Instead of a ListTile I have to use InkWell. It's a solution, but not an ideal one, because I lose some of the useful ListTile props (like leading, trailing, etc.)

Workaround code:

import 'package:flutter/material.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: ReorderableListView(
        onReorder: (oldIndex, newIndex) {},
        children: const [
          ListRow(key: ValueKey('0'), text: '000000'),
          ListRow(key: ValueKey('1'), text: '111111'),
          ListRow(key: ValueKey('2'), text: '222222'),
        ],
      )),
    );
  }
}

class ListRow extends StatelessWidget {
  const ListRow({super.key, required this.text});

  final String text;

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(10.0),
      child: InkWell(
        hoverColor: Colors.blue,
        onTap: () {},
        child: Row(
          children: [
            const Expanded(
              flex: 2,
              child: Text('HelloWorld'),
            ),
            Expanded(
                flex: 4,
                child: Align(
                  alignment: Alignment.centerLeft,
                  child: Container(
                    color: Colors.red,
                    margin: EdgeInsets.zero,
                    child: Padding(
                      padding: const EdgeInsets.all(8.0),
                      child: Text(text),
                    ),
                  ),
                ))
          ],
        ),
      ),
    );
  }
}

Thanks for the update. This isn't specific to web, as, on desktop (macos) as well, I see same behavior.
