TODO: write android documentation write iOS documentation write unit tests make a basic iOS and Android Example Application


import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:nearby_messages_api/nearby_messages_api.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  _MyAppState createState() => _MyAppState();

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';

  static void onFound(dynamic arguments) {

  static void onLost(dynamic arguments) {

  NearbyMessagesApi nearbyMessagesApi = NearbyMessagesApi(onFound, onLost);

  void initState() {

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      platformVersion = await nearbyMessagesApi.platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';

    await nearbyMessagesApi.backgroundSubscribe();
//    MessageReceiver receiver = new MessageReceiver();
//    receiver.onMessageReceived.listen((String msg) => print(msg));

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;

  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        body: Center(
          child: Text('Running on: $_platformVersion\n'),

Health issues and suggestions

Document public APIs. (-1 points)

8 out of 8 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.

Format lib/nearby_messages_api.dart.

Run flutter format to format lib/nearby_messages_api.dart.

Maintenance suggestions

The package description is too short. (-20 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.
