dependencies:

class ColorPickerDialog extends StatefulWidget {
  @override
  _ColorPickerDialogState createState() => _ColorPickerDialogState();
}

class _ColorPickerDialogState extends State<ColorPickerDialog> {
  Color selectedColor = Colors.red; // 默认选中的颜色

  @override
  Widget build(BuildContext context) {
    return AlertDialog(
      title: Text('选择颜色'),
      content: MaterialColorPicker(
        onColorChange: (Color color) {
          setState(() {
            selectedColor = color;
          });
        },
        selectedColor: selectedColor,
      ),
      actions: [
        FlatButton(
          child: Text('确定'),
          onPressed: () {
            // 在这里处理选中的颜色
            Navigator.of(context).pop(selectedColor);
          },
        ),
        FlatButton(
          child: Text('取消'),
          onPressed: () {
            Navigator.of(context).pop();
          },
        ),
      ],
    );
  }

FlatButton(
  child: Text('选择颜色'),
  onPressed: () {
    showDialog(
      context: context,
      builder: (BuildContext context) {
