flutter_mobile_vision_face_api #

Flutter plugin for google mobile vision face api.

Current Release is for Android only. #

This plugin helps to detect face in a captured picture and returns the path of the picture.

Dependencies #

Add the below line in pubspec.yaml. For the latest version, please visit https://pub.dev/packages/flutter_mobile_vision_api_face

flutter_mobile_vision_api_face: ^0.0.3

Permission

Need to add the below permission in AndroidManifest.xml

<uses-feature android:name="android.hardware.camera" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Since google mobile vision api is used in this library to detect face, need to add the below lines in AndroidManifest.xml inside the Application tag

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

<meta-data
    android:name="com.google.android.gms.vision.DEPENDENCIES"
    android:value="face" />

After adding the permissions and meta tags, need to add the activity developed in this plugin.

 <activity android:name="com.flutter.vision.flutter_mobile_vision_face_api.face.CameraActivity" />
 <activity android:name="com.flutter.vision.flutter_mobile_vision_face_api.face.PreviewPicture" />

Make Sure Minimum SDK version is 21 .

Finally add the below code in your dart file,

FlutterMobileVisionFaceApi.face();

0.0.1 #

  • Initial release for android only.

  • Fixed the issues

Health issues and suggestions

Document public APIs. (-1 points)

5 out of 5 API elements have no dartdoc comment.Providing good documentation for libraries, classes, functions, and other API elements improves code readability and helps developers find and use your API.

Maintenance suggestions

The package description is too short. (-11 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
