📖 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,
    );
  };
// [...]

Take a photo 🎉

await _pictureController.takePicture('THE_IMAGE_PATH/myimage.jpg');

Live image stream

The property imagesStreamBuilder allows you to get an imageStream once the camera is ready. Don't try to show all these images on Flutter UI as you won't have time to refresh UI fast enough. (there is too much images/sec).

CameraAwesome(
    ...
    imagesStreamBuilder: (imageStream) {
        /// listen for images preview stream
        /// you can use it to process AI recognition or anything else...
        print("-- init CamerAwesome images stream");
    },
)
