Flutter安全屏幕插件tbib_secure_screen的使用

Flutter安全屏幕插件tbib_secure_screen的使用

插件介绍

这个插件用于在保存截图或录制屏幕时，屏幕会显示空白。

开始使用

• Android配置：无需进行任何操作。
• iOS配置：前往 AppDelegate.swift 文件。

import UIKit
import Flutter
import tbib_secure_screen

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
      TbibSecureScreenPlugin.register(with: self.registrar(forPlugin: "tbib_secure_screen")!)
      TbibSecureScreenPlugin.shared?.initSecure()
      GeneratedPluginRegistrant.register(with: self)
      return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }

  override func applicationWillResignActive(
    _ application: UIApplication
  ) {
     TbibSecureScreenPlugin.shared?.blurScreen()
  }
  override func applicationDidBecomeActive(
    _ application: UIApplication
  ) {
     TbibSecureScreenPlugin.shared?.removeBlurScreen()
  }
}

注意事项

在 iOS 上，屏幕将在应用程序中的任何地方变为空白，而不是特定的屏幕，这意味着它将自动激活。

在 Android 上，工作在特定的屏幕上。

在 Flutter (Android) 中激活插件

你需要调用以下代码来激活插件：

TBIBSecureScreen().setSecureScreen();

在 Flutter (Android) 中禁用插件

你需要调用以下代码来禁用插件：

TBIBSecureScreen().setUnsecureScreen();

示例代码

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:tbib_secure_screen/tbib_secure_screen.dart';

void main() {
  TBIBSecureScreen().setSecureScreen();
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  final _tbibSecureScreenPlugin = TBIBSecureScreen();

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Text('Running on: $_platformVersion\n'),
        ),
      ),
    );
  }

  // 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.
    // We also handle the message potentially returning null.
    try {
      platformVersion = await _tbibSecureScreenPlugin.getPlatformVersion() ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // 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;
    });
  }

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
  }
}
