tflite

A Flutter plugin for accessing TensorFlow Lite. Supports both iOS and Android.

Installation

Add tflite as a dependency in your pubspec.yaml file.

Android

In android/app/build.gradle file add the following setting in android block.

    aaptOptions {
        noCompress 'tflite'
    }

iOS

If you get error like "'vector' file not found", please open ios/Runner.xcworkspace in Xcode, click Runner > Tagets > Runner > Build Settings, search Compile Sources As, change the value to Objective-C++;

Usage

  1. Create a assets folder and place your label file and model file in it. In pubspec.yaml add:
  assets:
   - assets/labels.txt
   - assets/mobilenet_v1_1.0_224.tflite
  1. Import the library:
import 'package:tflite/tflite.dart';
  1. Load the model and labels:
String res = await Tflite.loadModel(
  model: "assets/mobilenet_v1_1.0_224.tflite",
  labels: "assets/labels.txt",
);
  1. 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
  imageStd: 127.5,  // defaults to 1.0
  numResults: 6,    // defaults to 5
  threshold: 0.05,  // defaults to 0.1
  numThreads: 1,    // defaults to 1
);
  1. Release resources:
await Tflite.close();

Document public APIs (-10 points)

5 out of 5 API elements (library, class, field or method) have no adequate dartdoc content. Good documentation improves code readability and discoverability through search.

Maintenance suggestions

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

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