问题描述
我目前正在为我的颤振应用程序做 CI/CD，但是当我这样做时flutter test
，发生了这些异常，

protocol contract.
The following failures was detected:
* getMinIntrinsicWidth(Infinity) returned a non-finite value: Infinity
* getMaxIntrinsicWidth(Infinity) returned a non-finite value: Infinity
* getMinIntrinsicHeight(Infinity) returned a non-finite value: Infinity
* getMaxIntrinsicHeight(Infinity) returned a non-finite value: Infinity

* getMinIntrinsicHeight(800.0) returned a non-finite value: Infinity
* getMaxIntrinsicHeight(800.0) returned a non-finite value: Infinity
If you are not writing your own RenderBox subclass, then this is not
your fault. Contact support: https://github.com/flutter/flutter/issues/new?template=BUG.md

══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞════════════════════════════════════════════════════
The following message was thrown:
Multiple exceptions (7) were detected during the running of the current test, and at least one was
unexpected.
════════════════════════════════════════════════════════════════════════════════════════════════════
00:08 +0 -1: test [E]
Test failed. See exception logs above.
The test description was: test
00:08 +0 -1: Some tests failed.
class AppFullHeightBackgroundWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Transform.scale(
scale: 1.5,
origin: Offset(-100, 175),
child: Image.asset(
AppDrawables.background,
width: double.infinity,
height: double.infinity,
fit: BoxFit.cover,
),
);
}
我尽量避免将所有的 double.infinity 更改为有限值，因为我使用了很多 double.infinity。该代码适用于真实设备。
