当 LinearProgressIndicator 放在行内时应用程序崩溃

Question

我的Flutter项目中有如下代码：

           Row(
                children: <Widget>[
                 Text("data"),
                 LinearProgressIndicator(),
                ],
              )

仅此一项就足以导致错误：

════════ Exception caught by rendering library ═════════════════════════════════
RenderBox was not laid out: RenderRepaintBoundary#d2962 NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
'package:flutter/src/rendering/box.dart':
package:flutter/…/rendering/box.dart:1
Failed assertion: line 1978 pos 12: 'hasSize'

有什么想法吗？

Answer 1

SizedBox(
        width: 100.0,
        child: LinearProgressIndicator(),
        );
