Darwin Camera

Darwin camera makes it super easy to add camera to your Flutter app. It uses the official camera plugin implementation underneath.

  • Captures RAW image at maximum resolution supported by the device camera.
  • Provides a toggle between front and back camera.
    • You can configure what it defaults to on opening.
  • Provides configuration to set quality of the captured image.
  • Provides a minimal UI for the reviewing the capture before saving image.
  • Supports both Android and iOS.
Camera Stream Preview Captured Image
Press the white circular button to capture image. Press the green button to save the image.
Press the button at the bottom right to toggle camera. Press the close button to discard the captured image.

Getting Started

In your flutter project add darwin_camera as a dependency in pubspec.yaml:

dependencies:
  ...
  darwin_camera:
    git: https://github.com/atlanhq/darwin-camera

iOS

Add two rows to the ios/Runner/Info.plist:

  • one with the key Privacy - Camera Usage Description and a usage description.
  • and one with the key Privacy - Microphone Usage Description and a usage description.

Or in text format add the key:

<key>NSCameraUsageDescription</key>
<string>Can I use the camera please?</string>
<key>NSMicrophoneUsageDescription</key>
<string>Can I use the mic please?</string>

Android

Change the minimum Android sdk version to 21 (or higher) in your android/app/build.gradle file.

minSdkVersion 21

Usage example

import 'package:darwin_camera/darwin_camera.dart';

 DarwinCameraResult result = await Navigator.push(
   context,
   MaterialPageRoute(
     builder: (context) => DarwinCamera(
       cameraDescription: cameraDescription,
       filePath: filePath,
       resolution: ResolutionPreset.high,
       defaultToFrontFacing: false,
       quality: 90,
     ),
   ),
 );

if (result != null && result.isFileAvailable) {
   /// File object returned by Camera.
   print(result.file);
   /// Path where the file is faced. 
   print(result.file.path);
 }

DarwinCamera configuration

This widget captures an image and save it at the path provided by you.

DarwinCamera({
  
  ///
  /// Flag to enable/disable image compression.
  bool enableCompression = false, 
  
  ///
  /// Disables swipe based native back functionality provided by iOS.
  bool disableNativeBackFunctionality = false,
  
  /// @Required
  /// List of cameras availale in the device.
  /// 
  /// How to get the list available cameras?
  /// `List<CameraDescription> cameraDescription = await availableCameras();`
  List<CameraDescription> cameraDescription, 
  
  /// @Required
  
  /// Path where the image file will be saved.
  String filePath, 
  
  /// 
  /// Resolution of the image captured
  /// Possible values:
  /// 1. ResolutionPreset.high
  /// 2. ResolutionPreset.medium
  /// 3. ResolutionPreset.low
  ResolutionPreset resolution = ResolutionPreset.high, 

  ///
  /// Open front camera instead of back camera on launch.
  bool defaultToFrontFacing = false;

  ///
  /// Decides the quality of final image captured.
  /// Possible values `0 - 100`
  int quality = 90;

})
