create_user: zhengzaihong email:1096877329@qq.com create_date: 2025-12-26 create_time: 17:24 describe: 可控角度旋转组件 / Controllable Angle Rotation Component

支持配置旋转角度并带动画过渡的组件 Component with configurable rotation angle and animation transition

功能特性 / Features

🎯 精确控制旋转角度 / Precise angle control
🎬 平滑的动画过渡 / Smooth animation transition
🔄 支持动态更新角度 / Dynamic angle updates
⚙️ 可自定义动画时长 / Customizable animation duration

基础示例 / Basic Example

// 简单旋转
RotateView(
  angle: 45,
  child: Icon(Icons.arrow_forward, size: 50),
)

// 动态旋转
class MyWidget extends StatefulWidget {
  @override
  _MyWidgetState createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  double angle = 0;

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        RotateView(
          angle: angle,
          duration: Duration(milliseconds: 500),
          child: Icon(Icons.navigation, size: 50),
        ),
        Slider(
          value: angle,
          min: 0,
          max: 360,
          onChanged: (value) {
            setState(() => angle = value);
          },
        ),
      ],
    );
  }
}

// 箭头指示器
RotateView(
  angle: 90,
  child: Icon(Icons.arrow_upward),
)

// 自定义动画时长
RotateView(
  angle: 180,
  duration: Duration(milliseconds: 800),
  child: Container(
    width: 50,
    height: 50,
    color: Colors.blue,
  ),
)

注意事项 / Notes

angle 范围 0-360 度 / Angle range 0-360 degrees
角度改变时会自动播放动画 / Auto-animates on angle change
使用 Curves.easeOut 曲线 / Uses Curves.easeOut curve
