Flutter相机功能插件camerawesome_fork的使用

📸 将相机体验嵌入到自己的应用中不应该那么复杂。这是一个用于集成出色Android/iOS相机体验的Flutter插件。

这个包为您提供了一个可以在您的应用中使用的完全可自定义的相机体验。您可以使用我们内置的界面或根据需要进行自定义。

Fork of camerawesome package

此插件是camerawesome包的一个分叉版本。

以下是一个完整的示例代码，展示了如何在Flutter应用中使用camerawesome_fork插件：

import 'dart:io';

// import 'package:better_open_file/better_open_file.dart';
import 'package:camerawesome_fork/camerawesome_plugin.dart';
import 'package:camerawesome_fork/pigeon.dart';
import 'package:flutter/material.dart';
import 'package:path_provider/path_provider.dart';

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

class CameraAwesomeApp extends StatelessWidget {
  const CameraAwesomeApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: 'camerAwesome',
      home: CameraPage(),
    );
  }
}

class CameraPage extends StatelessWidget {
  const CameraPage({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        color: Colors.white,
