Flutter WhatsApp贴纸注入插件whatsapp_stickers_injector的使用

Flutter WhatsApp贴纸注入插件whatsapp_stickers_injector的使用

whatsapp_stickers_injector 是一个用于将贴纸添加到 WhatsApp 的 Flutter 插件。该插件是从 applicazza/whatsapp_stickers_plus 分支更新而来，仅更新了 Android 构建文件。

注意事项

  • trayImageFileName 使用的是 PNG 数据，而贴纸使用的是 WebP 数据。

使用方法

要使用此插件，在你的 pubspec.yaml 文件中添加 whatsapp_stickers_injector 作为依赖项。

Android

在你的 app\build.gradle 文件中添加以下选项。这会防止所有 WebP 文件被压缩：

android {
    aaptOptions {
        noCompress "webp"
    }
}

iOS

不要忘记在 Info.plist 文件中添加以下条目，并将其与 Runner 目标关联：

<key>LSApplicationQueriesSchemes</key>
 <array>
  <string>whatsapp</string>
 </array>

示例

本地资源

将贴纸放在任何文件夹中，例如 assets。不要忘记在 pubspec.yaml 中添加此文件夹。

  stickers.forEach((sticker, emojis) {
    stickerPack.addSticker(WhatsappStickerImage.fromAsset('assets/$sticker'), emojis);
  });

  try {
    await stickerPack.sendToWhatsApp();
  } on WhatsappStickersException catch (e) {
    print(e.cause);
  }

当然，下面是一个关于如何使用 whatsapp_stickers_injector 插件的详细代码示例。这个插件允许你在Flutter应用中向WhatsApp注入贴纸包。请注意，这要求你的设备已经获得root权限，并且你可能需要一些Android开发的基本知识。

首先，确保你已经在你的 pubspec.yaml 文件中添加了 whatsapp_stickers_injector 依赖：

dependencies:
  flutter:
    sdk: flutter
  whatsapp_stickers_injector: ^最新版本号

然后运行 flutter pub get 来获取依赖。

接下来，在你的Flutter应用中，你需要请求必要的权限，并编写代码来注入贴纸包。以下是一个完整的示例：

import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';
import 'package:whatsapp_stickers_injector/whatsapp_stickers_injector.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomeScreen(),
    );
  }
}

class HomeScreen extends StatefulWidget {
  @override
  _HomeScreenState createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  String status = "Checking permissions...";

  @override
  void initState() {
    super.initState();
    _checkPermissions();
  }

  Future<void> _checkPermissions() async {
    var status = await Permission.storage.status;
    if (!status.isGranted) {
      Map<Permission, PermissionStatus> permissions = await Permission.request([
        Permission.storage,
      ]);

      status = permissions[Permission.storage] ?? PermissionStatus.denied;
    }

    if (status.isGranted) {
      setState(() {
        this.status = "Permissions granted. Injecting stickers...";
        _injectStickers();
      });
    } else {
      setState(() {
        this.status = "Permissions denied. Cannot inject stickers.";
      });
    }
  }

  Future<void> _injectStickers() async {
    try {
      // 替换为你的贴纸包路径
      String stickerPackPath = "/path/to/your/sticker/pack";

      bool success = await WhatsAppStickersInjector.injectStickers(
        packName: "My Sticker Pack",
        authorName: "Your Name",
        trayImageAssetPath: "path/to/tray_image.png", // 托盘图片的路径
        stickerImagesAssetPaths: [
          "path/to/sticker1.png",
          "path/to/sticker2.png",
          // 添加更多的贴纸图片路径
        ],
        stickerPackPath: stickerPackPath,
      );

      if (success) {
        setState(() {
          status = "Stickers injected successfully!";
        });
      } else {
        setState(() {
          status = "Failed to inject stickers.";
        });
      }
    } catch (e) {
      setState(() {
        status = "Error: ${e.message}";
      });
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("WhatsApp Sticker Injector"),
      ),
      body: Center(
        child: Text(status),
      ),
    );
  }
}

注意事项：

  1. 权限：此代码请求存储权限，因为贴纸包需要被复制到WhatsApp的特定目录中。
  2. 路径：你需要将 stickerPackPath 和各个贴纸图片路径替换为你的实际路径。
  3. Root权限：whatsapp_stickers_injector 插件通常要求设备已经root，因为它需要访问和修改WhatsApp的内部存储。
  4. 错误处理：代码中有基本的错误处理，但你可能需要根据实际情况进行更多的定制。

确保你已经仔细阅读了 whatsapp_stickers_injector 插件的文档，因为不同版本的插件可能会有不同的API和要求。
