Getting started

To begin with, it's very simple, just import and instantiate SimpleCamera and then initialize it according to the example, after that you can use SimpleCameraPreview or create your own screen by calling simpleCamera.buildPreview()

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  var simpleCamera = SimpleCamera();

  @override
  void initState() {
    super.initState();
    initSimpleCamera();
  }

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

  void initSimpleCamera() async {
    try {
      // Here you initialize the camera and pass some options, such as resolution, image format, etc..
      // If it does not inform any camera description, by default it starts with the front camera
      // To learn more, see the documentation.
      simpleCamera.initializeCamera().then((value) {
        setState(() {});
      });
    } catch (e) {
      // Important
      // Here you must give the permissions to access the device camera and or audio
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SimpleCameraPreview(
        simpleCamera: simpleCamera,
        isFull: true,
        onPressedGallery: () {},
        onPressedVideoRecording: (xfile) {
          if (kDebugMode) {
            print(xfile?.name);
          }
        },
        onPressedTakePicture: (xfile) {
          if (kDebugMode) {
            print(xfile?.name);
          }
        },
      ),
    );
  }
}
