# Flutter Camera Ml Vision
[](https://pub.dartlang.org/packages/flutter_camera_ml_vision)
A Flutter package for iOS and Android to show a preview of the camera and detect things with Firebase ML Vision.
## Installation
First, add `flutter_camera_ml_vision` as a dependency.
```yaml
...
dependencies:
flutter:
sdk: flutter
flutter_camera_ml_vision: ^2.2.4
...
```
## Configure Firebase
You must also configure Firebase for each platform project: Android and iOS (see the `example` folder or https://firebase.google.com/codelabs/firebase-get-to-know-flutter#3 for step by step details).
### 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:
```
NSCameraUsageDescription
Can I use the camera please?
NSMicrophoneUsageDescription
Can I use the mic please?
```
If you're using one of the on-device APIs, include the corresponding ML Kit library model in your Podfile. Then run pod update in a terminal within the same directory as your Podfile.
```
pod 'Firebase/MLVisionBarcodeModel'
pod 'Firebase/MLVisionFaceModel'
pod 'Firebase/MLVisionLabelModel'
pod 'Firebase/MLVisionTextModel'
```
### Android
Change the minimum Android sdk version to 21 (or higher) in your `android/app/build.gradle` file.
```
minSdkVersion 21
```
_ps: This is due to the dependency on the camera plugin._
If you're using the on-device `LabelDetector`, include the latest matching [ML Kit: Image Labeling](https://firebase.google.com/support/release-notes/android) dependency in your app-level `build.gradle` file.
```gradle
android {
dependencies {
// ...
api 'com.google.firebase:firebase-ml-vision-image-label-model:19.0.0'
}
}
```
If you receive compilation errors, try an earlier version of [ML Kit: Image Labeling](https://firebase.google.com/support/release-notes/android).
Optional but recommended: If you use the on-device API, configure your app to automatically download the ML model to the device after your app is installed from the Play Store. To do so, add the following declaration to your app's `AndroidManifest.xml` file:
```xml
...
```
## Usage
### 1. Example with Barcode
```dart
CameraMlVision>(
detector: FirebaseVision.instance.barcodeDetector().detectInImage,
onResult: (List barcodes) {
if (!mounted || resultSent) {
return;
}
resultSent = true;
Navigator.of(context).pop(barcodes.first);
},
)
```
`CameraMlVision` is a widget that shows the preview of the camera. It takes a detector as a parameter here we pass the `detectInImage` method of the `BarcodeDetector` object.
The detector parameter can take all the different FirebaseVision Detector. Here is a list :
```
FirebaseVision.instance.barcodeDetector().detectInImage
FirebaseVision.instance.cloudLabelDetector().detectInImage
FirebaseVision.instance.faceDetector().processImage
FirebaseVision.instance.labelDetector().detectInImage
FirebaseVision.instance.textRecognizer().processImage
```
Then when something is detected the onResult callback is called with the data in the parameter of the function.
### Exposed functionality from CameraController
We expose some functionality from the CameraController class here a list of these :
- value
- prepareForVideoRecording
- startVideoRecording
- stopVideoRecording
- takePicture
