A Flutter plugin with common methods used in google_ml_kit.

Getting Started

Before you get started read about the requirements and known issues of this plugin here.

Usage

Creating an InputImage

From path:

final inputImage = InputImage.fromFilePath(filePath);

From file:

final inputImage = InputImage.fromFile(file);

From bytes:

final inputImage = InputImage.fromBytes(bytes: bytes, inputImageData: inputImageData);

From CameraImage (if you are using the Camera plugin):

import 'package:google_mlkit_commons/google_mlkit_commons.dart';

final camera; // your camera instance

final WriteBuffer allBytes = WriteBuffer();
for (final Plane plane in cameraImage.planes) {
  allBytes.putUint8List(plane.bytes);
}
final bytes = allBytes.done().buffer.asUint8List();

final Size imageSize = Size(cameraImage.width.toDouble(), cameraImage.height.toDouble());

final InputImageRotation imageRotation =
    InputImageRotationValue.fromRawValue(camera.sensorOrientation);

final InputImageFormat inputImageFormat =
    InputImageFormatValue.fromRawValue(cameraImage.format.raw);

final planeData = cameraImage.planes.map(
  (Plane plane) {
    return InputImagePlaneMetadata(
      bytesPerRow: plane.bytesPerRow,
      height: plane.height,
      width: plane.width,
    );
  },
).toList();

final inputImageData = InputImageData(
  size: imageSize,
  imageRotation: imageRotation,
  inputImageFormat: inputImageFormat,
  planeData: planeData,
);

final inputImage = InputImage.fromBytes(bytes: bytes, inputImageData: inputImageData);
