如果我运行此代码段：

await tester.enterText(
        find.byKey(Key('titleControlKey')), 'Sample Account 1');
await tester.enterText(find.byKey(Key('usernameControlKey')), 'username1');

或者这个：

await tester.enterText(
        find.byKey(Key('titleControlKey')), 'Sample Account 1');
await tester.enterText(find.byKey(Key('passwordControlKey')), 'password1');

它都有效。

但如果我运行三个：

await tester.enterText(
        find.byKey(Key('titleControlKey')), 'Sample Account 1');
await tester.enterText(find.byKey(Key('usernameControlKey')), 'username1');
await tester.enterText(find.byKey(Key('passwordControlKey')), 'password1');

测试将失败并产生此错误：

两个 tester.enterText 之间必须有一些稳定时间才能正常工作。根据您的需要添加这些。

        await tester.pump();
        await tester.pumpAndSettle();
        await tester.pump(Duration(seconds: 3));

例子

await tester.enterText(
    find.byKey(Key('titleControlKey')), 'Sample Account 1');
await tester.pumpAndSettle();
await tester.enterText(find.byKey(Key('usernameControlKey')),'username1');
await tester.pumpAndSettle();
await tester.enterText(find.byKey(Key('passwordControlKey')), 'password1');
await tester.pump(Duration(seconds: 3));

我刚刚解决了我自己的问题。因为 TextFields 在ListView小部件内部，当屏幕键出现时，其他 TextField 小部件不可见。所以我所做的是向下滚动表单tester.fling()以使密码TextField可见。

await tester.enterText(
        find.byKey(Key('titleControlKey')), 'Sample Account 1');
await tester.pumpAndSettle();
await tester.enterText(find.byKey(Key('usernameControlKey')), 'username1');
await tester.pumpAndSettle();
await tester.fling(listFinder, const Offset(0, -500), 10000);
await tester.pumpAndSettle();
await tester.enterText(find.byKey(Key('passwordControlKey')), 'password1');
await tester.pump(Duration(seconds: 2));
