Face Finder plugin

A flutter plugin to display a live camera view, detect faces, and HTTP POST them to a URL.


  • iOS only (all PRs accepted)
  • Front camera: iPhone X or later
  • Back camera: iOS v11+


The following draws a camera view overtop of all layers in the app, with the following configuration:

import 'package:face_finder/face_finder.dart';
await FaceFinder.cameraViewer(
	[0, 0, 200, 400], 


This is mainly a proof of concept at this point, but I'm submitting it in case it's useful to someone. I couldn't find any example of Swift Flutter plugins that used UIViews, so I thought the code might be helpful for others. If anyone knows how to use textures in Swift, let me know ;)

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

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

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

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

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

  void initState() {

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    await FaceFinder.cameraViewer([0, 0, 0, 0], "https://requestbin.fullcontact.com/1f0qm7z1");

    // 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(() {

  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: const Text('Face Finder'),
        body: new Center(
          child: new Text('Loading camera...'),
