Usage #

To use this plugin, add mlkit as a dependency in your pubspec.yaml file.

Getting Started #

Check out the example directory for a sample app using Firebase Cloud Messaging.

Android Integration #

To integrate your plugin into the Android part of your app, follow these steps:

  1. Using the Firebase Console add an Android app to your project: Follow the assistant, download the generated google-services.json file and place it inside android/app. Next, modify the android/build.gradle file and the android/app/build.gradle file to add the Google services plugin as described by the Firebase assistant.

iOS Integration #

To integrate your plugin into the iOS part of your app, follow these steps:

  1. Using the Firebase Console add an iOS app to your project: Follow the assistant, download the generated GoogleService-Info.plist file, open ios/Runner.xcworkspace with Xcode, and within Xcode place the file inside ios/Runner. Don't follow the steps named "Add Firebase SDK" and "Add initialization code" in the Firebase assistant.

  2. Remove the use_frameworks! line from ios/Podfile (workaround for flutter/flutter#9694).

Dart/Flutter Integration #

From your Dart code, you need to import the plugin and instantiate it:

import 'package:mlkit/mlkit.dart';

FirebaseVisionTextDetector detector = FirebaseVisionTextDetector.instance;

// Detect form file/image by path
var currentLabels = await detector.detectFromPath(_file?.path);

// Detect from binary data of a file/image
var currentLabels = await detector.detectFromBinary(_file?.readAsBytesSync());

custom model interpreter

native sample code

import 'package:mlkit/mlkit.dart';
import 'package:image/image.dart' as img;

FirebaseModelInterpreter interpreter = FirebaseModelInterpreter.instance;
FirebaseModelManager manager = FirebaseModelManager.instance;
manager.registerCloudModelSource(
        FirebaseCloudModelSource(modelName: "mobilenet_v1_224_quant"));

var imageBytes = (await rootBundle.load("assets/mountain.jpg")).buffer;
img.Image image = img.decodeJpg(imageBytes.asUint8List());
image = img.copyResize(image, 224, 224);
var results = await interpreter.run(
                    "mobilenet_v1_224_quant",
                    FirebaseModelInputOutputOptions(
                        0,
                        FirebaseModelDataType.BYTE,
                        [1, 224, 224, 3],
                        0,
                        FirebaseModelDataType.BYTE,
                        [1, 1001]),
                    imageToByteList(image));

Uint8List imageToByteList(img.Image image) {
    var _inputSize = 224;
    var convertedBytes = new Uint8List(1 * _inputSize * _inputSize * 3);
    var buffer = new ByteData.view(convertedBytes.buffer);
    int pixelIndex = 0;
    for (var i = 0; i < _inputSize; i++) {
      for (var j = 0; j < _inputSize; j++) {
        var pixel = image.getPixel(i, j);
        buffer.setUint8(pixelIndex++, (pixel >> 16) & 0xFF);
        buffer.setUint8(pixelIndex++, (pixel >> 8) & 0xFF);
        buffer.setUint8(pixelIndex++, (pixel) & 0xFF);
      }
    }
    return convertedBytes;
  }
