推荐答案

下面是逐步在本地修改插件的步骤，插件名为： flutter_abc-0.4.1

Here is step by step of how to modify plugin locally, my plugin named: flutter_abc-0.4.1

1. 右键单击软件包/ plugin的导入文件名，选择在Finder
   中显示或按住CMD，然后单击该文件名以转到该文件，然后右键单击文件中的任何位置，然后选择在Finder中显示。

1. Right click on package/plugin's import file name, choose Reveal in Finder Or hold CMD + Click on that file name to go to that file, then Right click anywhere in the file and choose "Reveal in Finder".

通常它位于〜/ .pub-cache / hosted / pub.darlang.org / flutter_abc-0.4.1

将整个程序包文件夹复制到您的应用程序文件夹中

Copy whole package folder to your app folder

要轻松劫持文件，只需复制全部放入您的应用文件夹（与 pubspec.yaml 相同级别，而不在 lib 文件夹中），然后重命名版本：

For easy hijacking files, just copy all to your app folder (same level with pubspec.yaml, not in the lib folder), then renaming version:

例如： flutter_abc-0.4.1-hijacking

现在，您可以修改要在本地修复错误的任何内容。

Now you can modify whatever you want to fix bug locally.

修改pubspec.yaml以指向本地包

Modify pubspec.yaml to point to local package

打开项目pubspec.yaml
将依赖关系的路径更改为例如：

Open your project pubspec.yaml Change path of dependencies to, for example:

flutter_abc：
路径：./ flutter_abcd-0.4.1-hijacking /
