Simple Web Camera #

A Flutter package that provides a simple widget to access and take photos using the browser's camera functionality. This package is specifically designed for web applications and returns the captured photo as a base64 encoded string.

Features #

• Easy to integrate camera access and photo capture functionality for Flutter web apps.
• Returns a base64 encoded string of the captured image, ready to be used within your application.
• Customizable AppBar title and the option to center the title.
• Camera switching capability allows users to switch between multiple cameras. The switch camera button is intelligently shown only when more than one camera is available, enhancing the user interface and experience.

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:simple_web_camera/simple_web_camera.dart';

void main() {
  runApp(const MainApp());
}

class MainApp extends StatelessWidget {
  const MainApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: "Simple Web Camera Example",
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  String result = '';

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: [
            ElevatedButton(
              onPressed: () async {
                var res = await Navigator.push(
                  context,
                  MaterialPageRoute(
                    builder: (context) => const SimpleWebCameraPage(
                        appBarTitle: "Take a Picture", centerTitle: true),
                  ),
                );
                setState(() {
                  if (res is String) {
                    result = res;
                  }
                });
              },
              child: const Text("Take a picture"),
            ),
            const SizedBox(height: 16),
            const Text("Picture taken:"),
            if (result.isNotEmpty)
              Center(
                child: SizedBox(
                  width: 200, // Example width
                  height: 200, // Example height
                  child: Image.memory(
                    base64Decode(result),
                  ),
                ),
              ),
          ],
        ),
      ),
    );
  }
