Flutter 中如何更改 ListView 的发光效果颜色？

Answer 1

在这里阅读 GlowingOverscrollIndicator似乎您可以更改 ThemeData.accentColor 的值来更改过度滚动发光颜色。

您可以尝试使用类似的方法将 Theme 更改限制为仅 ListView

//store the current Theme to restore it later
final ThemeData defaultTheme = Theme.of(context);

Theme(
  //Inherit the current Theme and override only the accentColor property
  data: Theme.of(context).copyWith(
    accentColor: Colors.yellow
  ),
  child: ListView.builder(
      //suppose data it's an array of strings
      itemBuilder: (BuildContext context, int index) =>
          EntryItem(data[index], defaultTheme),
      itemCount: data.length,
  ),
);

//this is your class to render rows
class EntryItem extends StatelessWidget {
  const EntryItem(this.entry, this.defaultTheme);

  final String entry;
  final ThemeData defaultTheme;

  Widget _buildTiles(String entry) {
    return Theme(
      data: defaultTheme,
      child: Text(entry)
    );
  }

  @override
  Widget build(BuildContext context) {
    return _buildTiles(entry);
  }
}
