如何在不同屏幕尺寸上测试Flutter小部件？

您可以使用WidgetTester指定自定义表面尺寸

以下代码将运行屏幕尺寸为42x42的测试

import 'package:flutter/widgets.dart';import 'package:flutter_test/flutter_test.dart';void main() {  testWidgets("foo", (tester) async {    tester.binding.window.physicalSizeTestValue = Size(42, 42);    // resets the screen to its orinal size after the test end    addTearDown(tester.binding.window.clearPhysicalSizeTestValue);    // TODO: do something  });}
