  model: "assets/mobilenet_v1_1.0_224.tflite",
  labels: "assets/labels.txt",
);

4. Run the model on a image file:

var recognitions = await Tflite.runModelOnImage(
  path: filepath,   // required
  inputSize: 224,   // wanted input size, defaults to 224
  numChannels: 3,   // wanted input channels, defaults to 3
  imageMean: 127.5, // defaults to 117.0
