call method
Calls a function stored on this context's globalThis.
method 仅按 globalThis[method] 单个属性解析;app.run 不会被拆分为
嵌套路径。args 支持结构化值编解码器可转换的 Dart 值。
Implementation
Future<Object?> call(String method, List<Object?> args, {Duration? timeout}) {
_ensureOpen();
return _engine.call(method, args, timeout: timeout);
}
