####Flutter插件pivo的使用方法

初始化插件

String? licenseKey;
if (Platform.isAndroid) {
  licenseKey =
      '{"owner":"Pivo","platform":"android","plan":"pro","appIdentifier":"app.pivo.android.prosdkdemo","createdAt":1587528360,"expiredAt":2524575600,"signature":"KqyuZmlt5rOQynORymSI+o2hMRwPdWUcU/LPBqZAQQUJybEBaL7+LlWdReAcfnNyafStKjw607s2Jf79T3Nbhq/jpvTD/upGga2BqJYTOiOsUGpZe/vjDgR3iMad0IOdmEf/68hdvo70w0AObZ9xufO5rjMTXc/sXY43kQ40/KS9UQfICUzLi1zgnJNF+C08n5fKuY7vzEOFB8P6Id0UTRFrPVDTkzTpze7aUtkF0pvJ/F+8FnRMP2r004sGVsGREJYnvAAPnV76yPzy4jsBAc4qVxTY508FwL/AwtNN5n1gJAdpS9D+0HkK1bvaxwWCBZ0Kk67uqFjXSaiOBrN5vQ=="}';
} else {
  licenseKey =
      '{"owner":"Pivo","platform":"ios","plan":"pro","appIdentifier":"app.pivo.ios.prosdkdemo","createdAt":1589928528,"expiredAt":2537535600,"signature":"QCnY1ShAHgBRnxfkeLNesDhogCj8PtFavbeqIK/hpq0+2U1vVByvJHzYYqyD9MsqWkuhorYETmB3bGLfhQzuf1C/IYVTg6STXBu5xJJxGbchGT/YcEmnyhHMXg6kkXUUNHYQGu45iuk11olX6aaxNhVY+UatMW9V4hcBjalNoVnbQiID/Mk4jVYFw/e+lB/JX0/ALhQJb1GwsATrEbnwY4F6YNLfPyQ7AAiuf9VDa0tmf0XpV6EiRNYcuqHWta9n8Wft78iG4bxKCV7zF7VmbVI9a1wlOOXrv6bGFl85NVjtSecnai+difBqNz0QXFfD6uXoJqU9orAtc9hrI4caGg=="}';
}

await PivoPlatform.instance.unlockWithLicenseKey(licenseKey);

连接到设备

final devicesStream = PivoPlatform.instance.scanResults;
await PivoPlatform.instance.startScan();

// 监听流
devicesStream.listen((event) async {
  await PivoPlatform.instance.stopScan();

  // 连接到设备
  unawaited(PivoPlatform.instance.connect(
    event.first.device,
  ));
});

控制Pivo设备

// 获取支持的速度
final supportedSpeedsInSeconds =
  await PivoPlatform.instance.getSupportedSpeedsInSecondsPerRound();

// 向右转90度，以最高速度转动
await PivoPlatform.instance.turnRight(90, supportedSpeedsInSeconds.first);

// 等待3秒
await Future.delayed(Duration(seconds: 3));

// 向左转90度，以最高速度转动
await PivoPlatform.instance.turnLeft(90, supportedSpeedsInSeconds.first);

// 等待3秒
await Future.delayed(Duration(seconds: 3));

// 持续向左转动，以最高速度转动
await PivoPlatform.instance
              .turnLeftContinuously(supportedSpeedsInSeconds.first);

await Future.delayed(Duration(seconds: 3));

// 停止设备
await PivoPlatform.instance.stop();

// 持续向右转动，以最高速度转动
await PivoPlatform.instance
              .turnRightContinuously(supportedSpeedsInSeconds.first);

await Future.delayed(Duration(seconds: 3));

// 停止设备
await PivoPlatform.instance.stop();

从设备断开连接

await PivoPlatform.instance.disconnect();

当然，以下是一个基于假设性描述的Flutter自定义旋转动画插件pivo的使用示例。请注意，由于pivo是一个假设的插件，以下代码是基于插件可能提供的功能进行编写的，实际使用时需要根据pivo插件的官方文档进行调整。

首先，确保在pubspec.yaml文件中添加了对pivo插件的依赖（假设该插件已发布到pub.dev）：

dependencies:
  flutter:
    sdk: flutter
  pivo: ^x.y.z  # 替换为实际版本号

然后，运行flutter pub get以获取插件。

接下来，我们编写一个使用pivo插件的示例代码。假设pivo插件提供了一个Pivo小部件，用于创建自定义旋转动画。

import 'package:flutter/material.dart';
import 'package:pivo/pivo.dart';  // 假设pivo插件的导入路径

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Pivo Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text('Pivo Demo'),
        ),
        body: Center(
          child: CustomRotationAnimation(),
        ),
      ),
    );
  }
}

class CustomRotationAnimation extends StatefulWidget {
  @override
  _CustomRotationAnimationState createState() => _CustomRotationAnimationState();
}

class _CustomRotationAnimationState extends State<CustomRotationAnimation> with SingleTickerProviderStateMixin {
  late AnimationController _controller;
  late Animation<double> _animation;

  @override
  void initState() {
    super.initState();
    _controller = AnimationController(
      duration: const Duration(seconds: 2),
      vsync: this,
    )..repeat(reverse: true);

    _animation = Tween<double>(begin: 0.0, end: 360.0).animate(_controller);
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Pivo(  // 假设Pivo是插件提供的小部件
      animation: _animation,
      child: Container(
        width: 100,
        height: 100,
        decoration: BoxDecoration(
          color: Colors.blue,
          shape: BoxShape.circle,
        ),
        child: Center(
          child: Icon(
            Icons.arrow_circle_right,
            color: Colors.white,
          ),
        ),
      ),
    );
  }
}

在这个示例中，我们做了以下几件事：

导入pivo插件。
创建一个Flutter应用，并在主页面中放置了一个CustomRotationAnimation小部件。
CustomRotationAnimation是一个有状态的小部件，它使用AnimationController和Tween来创建一个从0到360度的旋转动画。
使用假设的Pivo小部件，将动画应用于一个容器（该容器包含一个旋转箭头图标）。

请注意，由于pivo是一个假设的插件，上述代码中的Pivo小部件及其属性（如animation）是基于假设的。在实际使用时，你需要查阅pivo插件的官方文档来了解其实际提供的小部件和属性。

如果pivo插件提供了其他自定义功能或属性，你可能需要根据官方文档进行相应的调整。
