滚动和点按在Flutter驱动程序中不起作用

问题描述

我正在编写集成测试。我想点击滚动小部件内的按钮，该按钮从屏幕上是不可见的（至少在底部）。为了实现这一点，我正在编写如下代码，但无法正常工作。

SerializableFinder dashboardScrollView = find.byValueKey('dashboard_scroll_view');
SerializableFinder transfer = find.byValueKey('transfer');

test('open beneficiaries screen ',() async {
  await scrollUntilVisible(dashboardScrollView,transfer);
  await driver.tap(transfer);
});

Future<void> waitFor(SerializableFinder finder,{ Duration timeout }) async {
  await sendCommand(WaitFor(finder,timeout: timeout));
}

Future<void> scroll(SerializableFinder finder,double dx,double dy,Duration duration,{ int frequency = 60,Duration timeout }) async {
  await sendCommand(Scroll(finder,dx,dy,duration,frequency,timeout: timeout));
}

Future<void> scrollUntilVisible(
    SerializableFinder scrollable,SerializableFinder item,{
      double alignment = 0.0,double dxScroll = 0.0,double dyScroll = 0.0,Duration timeout,}) async {
  assert(scrollable != null);
  assert(item != null);
  assert(alignment != null);
  assert(dxScroll != null);
  assert(dyScroll != null);
  assert(dxScroll != 0.0 || dyScroll != 0.0);


  bool isVisible = false;
  waitFor(item,timeout: timeout).then<void>((_) { isVisible = true; });
  await Future<void>.delayed(const Duration(milliseconds: 500));
  while (!isVisible) {
    await scroll(scrollable,dxScroll,dyScroll,const Duration(milliseconds: 100));
    await Future<void>.delayed(const Duration(milliseconds: 500));
  }

  return scrollIntoView(item,alignment: alignment);
}
