๐Ÿ“–ย  Installation and usage

Add the package in your pubspec.yaml

  camerawesome: ^1.3.0

Platform specific setup

  • iOS

Add these on ios/Runner/Info.plist:

<string>Your own description</string>

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

<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=""
  <uses-permission android:name="android.permission.RECORD_AUDIO" />

  <!-- Other declarations -->

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

<manifest xmlns:android=""
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

  <!-- Other declarations -->
โš ๏ธ 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, but class was expected

Import the package in your Flutter app

import 'package:camerawesome/camerawesome_plugin.dart';

๐Ÿ‘Œ Awesome built-in interface

Just use our builder. That’s all you need to create a complete camera experience within you app.

  saveConfig: SaveConfig.image(
    pathBuilder: _path(),
  onMediaTap: (mediaCapture) {;

CamerAwesome default UI

This builder can be customized with various settings:

  • a theme
  • builders for each part of the screen
  • initial camera setup
  • preview positioning
  • additional preview decoration
  • and more!

Here is an example:

Customized UI

Check the full documentation to learn more.

๐ŸŽจ Creating a custom interface

If the awesome() factory is not enough, you can use custom() instead.

It provides a builder property that lets you create your own camera experience.

The camera preview will be visible behind what you will provide to the builder.

  saveConfig: SaveConfig.image(pathBuilder: _path()),
  builder: (state, previewSize, previewRect) {
    // create your interface here

See more in documentation

Working with the custom builder

Here is the definition of our builder method.

typedef CameraLayoutBuilder = Widget Function(CameraState cameraState, PreviewSize previewSize, Rect previewRect);

The only thing you have access to manage the camera is the cameraState. Depending on which state is our camera experience you will have access to some different method. `previewSize` and `previewRect` might be used to position your UI around or on top of the camera preview.

How do CamerAwesome states work ?

Using the state you can do anything you need without having to think about the camera flow

  • On app start we are in PreparingCameraState
  • Then depending on the initialCaptureMode you set you will be PhotoCameraState or VideoCameraState
  • Starting a video will push a VideoRecordingCameraState
  • Stopping the video will push back the VideoCameraState

    Also if you want to use some specific function you can use the when method so you can write like this.

  onPhotoMode: (photoState) => photoState.start(),
  onVideoMode: (videoState) => videoState.start(),
  onVideoRecordingMode: (videoState) => videoState.pause(),

See more in documentation

๐Ÿ”ฌ Analysis mode

Use this to achieve:

  • QR-Code scanning.
  • Facial recognition.
  • AI object detection.
  • Realtime video chats. And much more ๐Ÿคฉ

Face AI

You can check examples using MLKit inside the example directory. The above example is from ai_analysis_faces.dart. It detects faces and draw their contours.

It’s also possible to use MLKit to read barcodes:

Barcode scanning

Check ai_analysis_barcode.dart and preview_overlay_example.dart for examples or the documentation.

How to use it

  saveConfig: SaveConfig.image(
    pathBuilder: _path(),
  onImageForAnalysis: analyzeImage,
  imageAnalysisConfig: AnalysisConfig(
        // Android specific options
        androidOptions: const AndroidAnalysisOptions.nv21(
            // Target width (CameraX will chose the closest resolution to this width)
            width: 250,
        // Wether to start automatically the analysis (true by default)
        autoStart: true,
        // Max frames per second, null for no limit (default)
        maxFramesPerSecond: 20,

MLkit recommands to use nv21 format for Android. bgra8888 is the iOS format For machine learning you don’t need full resolution images (720 or lower should be enough and makes computation easier)

Learn more about the image analysis configuration in the documentation .

Check also detailed explanations on how to use MLKit to read barcodes and detect faces.

โš ๏ธ On Android, some devices don’t support video recording and image analysis at the same time.

  • If they don’t, image analysis will be ignored.
  • You can check if a device has this capability by using CameraCharacteristics .isVideoRecordingAndImageAnalysisSupported(Sensors.back).

๐Ÿฝ Updating Sensor configuration

Through state you can access to a SensorConfig class.

Function Comment
setZoom changing zoom
setFlashMode changing flash between NONE,ON,AUTO,ALWAYS
setBrightness change brightness level manually (better to let this auto)
setMirrorFrontCamera set mirroring for front camera

All of this configurations are listenable through a stream so your UI can automatically get updated according to the actual configuration.

๐ŸŒ† Photo live filters

Apply live filters to your pictures using the built-in interface:

Built-in live filters

You can also choose to use a specific filter from the start:

  // other params
  filter: AwesomeFilter.AddictiveRed,

Or set the filter programmatically:

  builder: (cameraState, previewSize, previewRect) {
    return cameraState.when(
      onPreparingCamera: (state) =>
      const Center(child: CircularProgressIndicator()),
      onPhotoMode: (state) =>
          TakePhotoUI(state, onFilterTap: () {
      onVideoMode: (state) => RecordVideoUI(state, recording: false),
      onVideoRecordingMode: (state) =>
          RecordVideoUI(state, recording: true),

See all available filters in the documentation.
