📖  Installation and usage

Add the package in your pubspec.yaml

dependencies:
  flutter_generic_camera: ^0.0.1
  ...

Platform specific setup

• iOS

Add these on ios/Runner/Info.plist:

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

<key>NSMicrophoneUsageDescription</key>
<string>To enable microphone access when recording video</string>

<key>NSLocationWhenInUseUsageDescription</key>
<string>To enable GPS location access for Exif data</string>

• Android

Change the minimum SDK version to 21 (or higher) in android/app/build.gradle:

minSdkVersion 21

In order to be able to take pictures or record videos, you may need additional permissions depending on the Android version and where you want to save them. Read more about it in the official documentation.

WRITE_EXTERNAL_STORAGE is not included in the plugin starting with version 1.4.0.

If you want to record videos with audio, add this permission to your AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.yourpackage">
  <uses-permission android:name="android.permission.RECORD_AUDIO" />

  <!-- Other declarations -->
</manifest>

You may also want to save location of your pictures in exif metadata. In this case, add below permissions:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.example.yourpackage">
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

  <!-- Other declarations -->
</manifest>

⚠️ Overriding Android dependencies

Some of the dependencies used by CamerAwesome can be overriden if you have a conflict. Change these variables to define which version you want to use:

buildscript {
  ext.kotlin_version = '1.7.10'
  ext {
    // You can override these variables
    compileSdkVersion = 33
    minSdkVersion = 24 // 21 minimum
    playServicesLocationVersion = "20.0.0"
    exifInterfaceVersion = "1.3.4"
  }
  // ...
}

Only change these variables if you are sure of what you are doing.

For example, setting the Play Services Location version might help you when you have conflicts with other plugins. The below line shows an example of these conflicts:

java.lang.IncompatibleClassChangeError: Found interface com.google.android.gms.location.ActivityRecognitionClient, but class was expected

How to use it

GenericCameraConfiguration config = GenericCameraConfiguration(
    captureMode: AssetType.photo,
    canCaptureMultiplePhotos: true,
    cameraPosition: CameraPosition.front,
    cameraPhotoFlash: FlashMode.auto,
    cameraVideoTorch: TorchMode.auto, // In case capture mode video
  );
  var capturedData = await _flutterGenericCameraPlugin.openCamera(config);
  if (capturedData["captured_images"] != null) {
    debugPrint("Captured Image ${capturedData["captured_images"]}");
  } else if (capturedData["captured_video"] != null) {
    debugPrint("Captured Video ${capturedData["captured_video"]}");
  }

🐽 Updating Camera configuration

canCaptureMultiplePhotos	set true for caputre multiple photos
cameraPosition	change camera positon to front or back
cameraPhotoFlash	Utilize flash functionalities to improve image quality in low-light conditions.
