Camera Plugin #

A Flutter plugin for iOS and Android allowing access to the device cameras.

Note: This plugin is still under development, and some APIs might not be available yet. We are working on a refactor which can be followed here: issue

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.

First, add camera as a dependency in your pubspec.yaml file.

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

one with the key Privacy - Camera Usage Description and a 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>

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

minSdkVersion 21

Here is a small example flutter app displaying a full screen camera preview.

import 'dart:async'; import 'package:flutter/material.dart'; import 'package:camera/camera.dart'; List<CameraDescription> cameras; Future<void> main() async { WidgetsFlutterBinding.ensureInitialized(); cameras = await availableCameras(); runApp(CameraApp()); } class CameraApp extends StatefulWidget { @override _CameraAppState createState() => _CameraAppState(); } class _CameraAppState extends State<CameraApp> { CameraController controller; @override void initState() { super.initState(); controller = CameraController(cameras[0], ResolutionPreset.medium); controller.initialize().then((_) { if (!mounted) { return; } setState(() {}); }); } @override void dispose() { controller?.dispose(); super.dispose(); } @override Widget build(BuildContext context) { if (!controller.value.isInitialized) { return Container(); } return AspectRatio( aspectRatio: controller.value.aspectRatio, child: CameraPreview(controller)); } }
