flutter - 如何模拟对 RenderAndroidView 的点击？

问题描述

我需要在 RenderAndroidView （一个 GoogleMap 插件）的特定位置模拟点击，但我无法让它工作。

这是我迄今为止尝试过的一种变体：

GlobalKey googleMapKey = GlobalKey();

GoogleMap(
  key: googleMapKey,
  ... // etc.
)

final renderObj = googleMapKey.currentContext.findRenderObject();

if (renderObj is RenderBox) {
  BoxHitTestResult hitTestResult = BoxHitTestResult();

  if( renderObj.hitTest(hitTestResult, position: tapPosition) ){
    PointerEvent pointerEvent = PointerDownEvent(position: tapPosition);
    final hitTestEntry = hitTestResult.path.firstWhere((element) => element.target is RenderAndroidView);
    hitTestEntry.target.handleEvent(pointerEvent, hitTestEntry);
  }
}

这给了我以下错误：

'package:flutter/src/gestures/pointer_router.dart': Failed assertion: line 31 pos 12: '!routes.containsKey(route)': is not true.
I/flutter ( 2544): #0      _AssertionError._doThrowNew (dart:core-patch/errors_patch.dart:46:39)

I/flutter ( 2544): #6      _PlatformViewGestureMixin.handleEvent (package:flutter/src/rendering/platform_view.dart:726:27)

是否可以在 a 上的特定位置模拟点击RenderAndroidView，如果可以，如何？
