Flutter实现自定义相机界面_flutter拍照界面

先看图，无图无真相~

界面很简陋，可以根据自己的需求进行修改界面

自定义相册使用到的插件

  camera: 0.5.7+4
  permission_handler: 3.2.2
  path_provider: 1.6.0

主要代码

• 主界面：

class MyHomePage extends StatefulWidget {
   
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
   
  String imagePath;

  @override
  Widget build(BuildContext context) {
   
    return Scaffold(
      appBar: AppBar(title: Text("自定义camera"),),
      body: Container(
        width: double.infinity,
        height: double.infinity,
        alignment: Alignment.center,
        child: Column(
          children: <Widget>[
            RaisedButton(
              onPressed: (){
   
                requestPermission();
              },
              child: Text("自定义相机"),
            ),
            Container(
                width: 100,
                height: 100,
                margin: EdgeInsets.only(top: 50),
                alignment: Alignment.center,
                child: imagePath!=null?Image.asset(imagePath,):Text("未选择图片")
            )
          ],
        ),
      ),
    )
