如何使用GestureDetector在Flutter中平滑地旋转图像？

import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';

double angle = 0.0;

GestureDetector(
  onScaleUpdate: (ScaleUpdateDetails details) {
    setState(() {
      angle = details.rotation;
    });
  },
  child: Transform.rotate(
    angle: angle,
    child: Image.asset('assets/image.jpg'),  // 替换为你的图像路径
  ),
),

import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Smooth Image Rotation')),
        body: SmoothImageRotation(),
      ),
    );
  }
}

class SmoothImageRotation extends StatefulWidget {
  @override
  _SmoothImageRotationState createState() => _SmoothImageRotationState();
}

class _SmoothImageRotationState extends State<SmoothImageRotation> {
  double angle = 0.0;

  @override
  Widget build(BuildContext context) {
    return Center(
      child: GestureDetector(
        onScaleUpdate: (ScaleUpdateDetails details) {
          setState(() {
            angle = details.rotation;
          });
        },
        child: Transform.rotate(
          angle: angle,
          child: Image.asset('assets/image.jpg'),  // 替换为你的图像路径
        ),
      ),
    );
  }
}
