根因分析

原生平台插件未为指定通道注册预期的方法处理器，通常是由于缺少插件注册或方法名称错误。

English

The native platform plugin does not register the expected method handler for the given channel, often due to missing plugin registration or incorrect method name.

解决方案

  1. 确保插件的原生代码注册了方法通道。对于 Android，检查 MainActivity.kt：GeneratedPluginRegistrant.registerWith(flutterEngine)。对于 iOS，检查 AppDelegate.swift：GeneratedPluginRegistrant.register(with: self)。
  2. 运行 'flutter clean' 和 'flutter pub get' 以重置构建缓存并重新生成注册文件。
  3. 验证原生处理程序中的方法名称与 Flutter 调用的完全匹配（区分大小写）。

无效尝试

常见但无效的做法:

  1. Rebuilding the entire app without cleaning caches 40% 失败

    Stale build artifacts may still reference old plugin registrations; a clean build is needed.

  2. Manually editing generated plugin registrant files 70% 失败

    Registrant files are auto-generated and overwritten on rebuild; manual edits are lost.

  3. Adding the plugin again in pubspec.yaml without checking native setup 50% 失败

    The plugin is already declared; the issue is in native code registration, not Dart dependency.
