Flutter：如何在不复制整个文件的情况下调整/覆盖Flutter核心代码的属性？ [英] Flutter: how to adjust/override properties of the Flutter core code without copying entire files?
问题描述
此问题与以下StackOverflow问题有关：底页，其初始高度为屏幕的一半，如果滚动，则高度会增加到全屏
This question is related to the following StackOverflow issue: bottom sheet with initial height half of screen and if it scroll then height is increase to full screen
是关于Flutter代码在底部表格中设置的约束，我不希望这样。我了解上面链接中提到的解决方案，但是我不知道如何以一种很好的方式来实现它。
It is about a constraint that is set within the Flutter code about bottom sheets, that I do not want to have. I understand the solution mentioned in the link above, but I don't know how to implement it in a nice way.
现在，我的解决方案是从官方Flutter代码库中完全复制bottom_sheet.dart文件，并删除带有maxHeight属性的行169： https://github.com/flutter/ flutter / blob / 1ad538e454c77496fbd068b9e8b5f8b61c2f6d96 / packages / flutter / lib / src / material / bottom_sheet.dart＃L169
Right now my 'solution' is to completely copy the bottom_sheet.dart file from the official Flutter codebase and remove just the line 169 with the maxHeight property: https://github.com/flutter/flutter/blob/1ad538e454c77496fbd068b9e8b5f8b61c2f6d96/packages/flutter/lib/src/material/bottom_sheet.dart#L169
任何以更优雅的方式做到这一点的想法？
Any ideas to do this in a more elegant way?
谢谢！
推荐答案
您不能。如果要更改源，则必须克隆源。
You can't. You have to clone the sources if you want to make a change to them.
这部分是自愿的。 Flutter的目的是让您轻松地复制源代码并进行一些更改。
This is partially voluntary. Flutter is purposefully designed to easily let you copy the sources and make some changes.
如果这对解决方案来说太糟糕了，
If that's too bad of a solution, you can instead fork flutter.
Flutter很容易分叉，因为安装过程只不过是一个简单的git clone：
Flutter is very easy to fork, as the installation process is nothing but a simple git clone:
- 转到 http：// github .com / flutter / flutter
- 单击
叉子 - 替换您的使用此fork的本地SDK
- 对源进行更改
- go to http://github.com/flutter/flutter
- click on
fork - replace your local SDK with this fork
- make your change to the sources
