As part of implementing federated architecture and making the interface compatible with the web this version contains the following **breaking changes**:
|
||||
|
||||
Method changes in `CameraController`:
|
||||
- The `takePicture` method no longer accepts the `path` parameter, but instead returns the captured image as an instance of the `XFile` class;
|
||||
- The `startVideoRecording` method no longer accepts the `filePath`. Instead the recorded video is now returned as a `XFile` instance when the `stopVideoRecording` method completes;
|
||||
- The `stopVideoRecording` method now returns the captured video when it completes;
|
||||
- Added the `buildPreview` method which is now used to implement the CameraPreview widget.

||||

|
||||
|
||||
* Changed the order of the setters for `mediaRecorder` in `MediaRecorderBuilder.java` to make it more readable.
|
||||

## 0.3.0
|
||||
|
||||
* **Breaking change**. Migrate from the deprecated original Android Support
|
||||
Library to AndroidX. This shouldn't result in any functional changes, but it
|
||||
requires any Android apps using this plugin to [also
|
||||
migrate](https://developer.android.com/jetpack/androidx/migrate) if they're
|
||||
using the original support library.
|
||||
|

* Unregister the activity lifecycle callbacks when disposing the camera.
|
||||
|
||||
## 0.2.3
|
||||
|
||||
* Added path_provider and video_player as dev dependencies because the example uses them.
|
||||
* Updated example path_provider version to get Dart 2 support.
|
||||
|
||||

# Camera Plugin
|
||||
|
||||
<?code-excerpt path-base="excerpts/packages/camera_example"?>
|
||||
|
||||
[](https://pub.dev/packages/camera)
|
||||
|
||||
A Flutter plugin for iOS, Android and Web allowing access to the device cameras.
|
||||
|
||||
| | Android | iOS | Web |
|
||||
|----------------|---------|----------|------------------------|
|
||||
| **Support** | SDK 21+ | iOS 10+* | [See `camera_web `][1] |
|
||||
|
||||
## Features
|
||||
|
||||
* Display live camera preview in a widget.
|
||||
* Snapshots can be captured and saved to a file.
|
||||
* Record video.
|
||||
* Add access to the image stream from Dart.
|
||||
|
||||
## Installation
|
||||
|
||||
First, add `camera` as a [dependency in your pubspec.yaml file](https://flutter.dev/using-packages/).
|
||||
|
||||
### iOS
|
||||
|
||||
\* The camera plugin compiles for any version of iOS, but its functionality
|
||||
requires iOS 10 or higher. If compiling for iOS 9, make sure to programmatically
|
||||
check the version of iOS running on the device before using any camera plugin features.
|
||||
The [device_info_plus](https://pub.dev/packages/device_info_plus) plugin, for example, can be used to check the iOS version.
|
||||
|
||||
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.
|
||||
|
||||
If editing `Info.plist` as text, add:
|
||||
|
||||
```xml
|
||||
<key>NSCameraUsageDescription</key>
|
||||
<string>your usage description here</string>
|
||||
<key>NSMicrophoneUsageDescription</key>
|
||||
<string>your usage description here</string>
|
||||
```
|
||||
|
||||
### Android
|
||||
|
||||
Change the minimum Android sdk version to 21 (or higher) in your `android/app/build.gradle` file.
|
||||
|
||||
```groovy
|
||||
minSdkVersion 21
|
||||
```
|
||||
|
||||
It's important to note that the `MediaRecorder` class is not working properly on emulators, as stated in the documentation: https://developer.android.com/reference/android/media/MediaRecorder. Specifically, when recording a video with sound enabled and trying to play it back, the duration won't be correct and you will only see the first frame.
|
||||
|
||||
### Web integration
|
||||
|
||||
For web integration details, see the
|
||||
[`camera_web` package](https://pub.dev/packages/camera_web).
|
||||
|
||||
### Handling Lifecycle states
|
||||
|
||||
As of version [0.5.0](https://github.com/flutter/plugins/blob/main/packages/camera/CHANGELOG.md#050) of the camera plugin, lifecycle changes are no longer handled by the plugin. This means developers are now responsible to control camera resources when the lifecycle state is updated. Failure to do so might lead to unexpected behavior (for example as described in issue [#39109](https://github.com/flutter/flutter/issues/39109)). Handling lifecycle changes can be done by overriding the `didChangeAppLifecycleState` method like so:
|
||||
|
||||
<?code-excerpt "main.dart (AppLifecycle)"?>
|
||||
```dart
|
||||
@override
|
||||
void didChangeAppLifecycleState(AppLifecycleState state) {
|
||||
final CameraController? cameraController = controller;
|
||||
|
||||
// App state changed before we got the chance to initialize.
|
||||
if (cameraController == null || !cameraController.value.isInitialized) {
|
||||
return;
|
||||
}
|
||||
|
||||
if (state == AppLifecycleState.inactive) {
|
||||
cameraController.dispose();
|
||||
} else if (state == AppLifecycleState.resumed) {
|
||||
onNewCameraSelected(cameraController.description);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Handling camera access permissions
|
||||
|
||||
Permission errors may be thrown when initializing the camera controller, and you are expected to handle them properly.
|
||||
|
||||
Here is a list of all permission error codes that can be thrown:
|
||||
|
||||
- `CameraAccessDenied`: Thrown when user denies the camera access permission.
|
||||
|
||||
- `CameraAccessDeniedWithoutPrompt`: iOS only for now. Thrown when user has previously denied the permission. iOS does not allow prompting alert dialog a second time. Users will have to go to Settings > Privacy > Camera in order to enable camera access.
|
||||
|
||||
- `CameraAccessRestricted`: iOS only for now. Thrown when camera access is restricted and users cannot grant permission (parental control).
|
||||
|
||||
- `AudioAccessDenied`: Thrown when user denies the audio access permission.
|
||||
|
||||
- `AudioAccessDeniedWithoutPrompt`: iOS only for now. Thrown when user has previously denied the permission. iOS does not allow prompting alert dialog a second time. Users will have to go to Settings > Privacy > Microphone in order to enable audio access.
|
||||
|
||||
- `AudioAccessRestricted`: iOS only for now. Thrown when audio access is restricted and users cannot grant permission (parental control).
|
||||
|
||||
### Example
|
||||
|
||||
Here is a small example flutter app displaying a full screen camera preview.
|
||||
|
||||
<?code-excerpt "readme_full_example.dart (FullAppExample)"?>
|
||||
```dart
|
||||
import 'package:camera/camera.dart';
|
||||
import 'package:flutter/material.dart';
|
||||
|
||||
late List<CameraDescription> _cameras;
|
||||
|
||||
Future<void> main() async {
|
||||
WidgetsFlutterBinding.ensureInitialized();
|
||||
|
||||
_cameras = await availableCameras();
|
||||
runApp(const CameraApp());
|
||||
}
|
||||
|
||||
/// CameraApp is the Main Application.
|
||||
class CameraApp extends StatefulWidget {
|
||||
/// Default Constructor
|
||||
const CameraApp({Key? key}) : super(key: key);
|
||||
|
||||
@override
|
||||
State<CameraApp> createState() => _CameraAppState();
|
||||
}
|
||||
|
||||
class _CameraAppState extends State<CameraApp> {
|
||||
late CameraController controller;
|
||||
|
||||
@override
|
||||
void initState() {
|
||||
super.initState();
|
||||
controller = CameraController(_cameras[0], ResolutionPreset.max);
|
||||
controller.initialize().then((_) {
|
||||
if (!mounted) {
|
||||
return;
|
||||
}
|
||||
setState(() {});
|
||||
}).catchError((Object e) {
|
||||
if (e is CameraException) {
|
||||
switch (e.code) {
|
||||
case 'CameraAccessDenied':
|
||||
// Handle access errors here.
|
||||
break;
|
||||
default:
|
||||
// Handle other errors here.
|
||||
break;
|
||||
}
|
||||
}
|
||||
});
|
||||
}
|
||||
|
||||
@override
|
||||
void dispose() {
|
||||
controller.dispose();
|
||||
super.dispose();
|
||||
}
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context) {
|
||||
if (!controller.value.isInitialized) {
|
||||
return Container();
|
||||
}
|
||||
return MaterialApp(
|
||||
home: CameraPreview(controller),
|
||||
);
|
||||
}
|
||||
}
|
||||
```

# Launch Screen Assets
|
||||
|
||||
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
|
||||
|
||||
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
