如何在 flutter 中显示 listview inside alert

Question

我正在使用 rflutter_alert 插件来处理我使用 Flutter 的应用程序中的警报但是当我将 listView 用于参数内容时出现问题文本等其他小部件可以正常工作

我收到以下错误

Exception caught by rendering library ═════════════════════════════════════════════════════ The following assertion was thrown during performLayout(): RenderViewport does not support returning intrinsic dimensions.

Expanded(
  child: Card(
    child: ListView.builder(
        itemCount: content.length,
        itemBuilder: (ctx, index) {
          return ListTile(title: Text(content[index]["doctor_name"]),
          onTap: (){
            Alert(
              context: context,
              title: doctors[index]["doctor_name"],
              content: ListView(children: <Widget>[
                Text(doctors[index]["major"]),
                Text(doctors[index]["hospital"]),
              ],)
            ).show();
          },
          );
        }),
  ),
)

这是布线 url rflutter_alert

你能帮忙解决这个问题吗？

Answer 1

您可以尝试将其包装到容器中并设置 width/height

   onTap: (){
        Alert(
          context: context,
          title: doctors[index]["doctor_name"],
          content: Container(
            width: 100,
            height: 100,
            child: ListView(children: <Widget>[
               Text(doctors[index]["major"]),
               Text(doctors[index]["hospital"]),
          ],))
        ).show();

您需要在 ListView 的警报对话框中添加一个 shrinkWrap: true。

如下所示。

      ListView.builder(
          itemCount: 10,
          itemBuilder: (ctx, index) {
            return ListTile(
              title: Text('$index'),
              onTap: () {
                Alert(
                  context: context,
                  title: 'Title',
                  content: ListView(
                    shrinkWrap: true, // Like here
                    children: <Widget>[
                      Text('Test'),
                      Text('Test'),
                    ],
                  ),
                ).show();
              },
            );
          }),
