Installation and usage

Set permissions

iOS add these on ios/Runner/Info.plist file

<key>NSCameraUsageDescription</key>
<string>Your own description</string>

Android
- Set permissions before <application>
<uses-permission android:name=”android.permission.CAMERA” /> <uses-permission android:name=”android.permission.WRITE_EXTERNAL_STORAGE” />
- Change the minimum SDK version to 21 (or higher) in android/app/build.gradle
minSdkVersion 21

Import the package

import 'package:camerawesome/camerawesome_plugin.dart';

Define notifiers (if needed) & controller

ValueNotifier is a usefull change notifier from Flutter framework. It fires an event on all listener when value changes. Take a look here for ValueNotifier doc

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> with TickerProviderStateMixin {
  // [...]
  // Notifiers
  ValueNotifier<CameraFlashes> _switchFlash = ValueNotifier(CameraFlashes.NONE);
  ValueNotifier<Sensors> _sensor = ValueNotifier(Sensors.BACK);
  ValueNotifier<Size> _photoSize = ValueNotifier(null);

  // Controller
  PictureController _pictureController = new PictureController();
  // [...]
}

If you want to change a config, all you need is setting the value. CameraAwesome will handle the rest.

Example:

_switchFlash.value = CameraFlashes.AUTO

Create your camera

// [...]
@override
  Widget build(BuildContext context) {
    return CameraAwesome(
      testMode: false,
      onPermissionsResult: (bool result) { }
      selectDefaultSize: (List<Size> availableSizes) => Size(1920, 1080),
      onCameraStarted: () { },
      onOrientationChanged: (CameraOrientations newOrientation) { },
      zoom: 0.64,
      sensor: _sensor,
      photoSize: _photoSize,
      switchFlashMode: _switchFlash,
      orientation: DeviceOrientation.portraitUp,
      fitted: true,
    );
  };
// [...]
