如何修改插件 Dart 代码 Flutter? [英] How to modify plugins Dart code Flutter?

问题描述

我正在开发 Flutter 应用程序，它使用 map_view 插件.我想通过修改源代码为插件添加新功能.通过 Flutter 安装插件后，如何在我的项目中找到插件的实际源代码?

Flutter 中插件是如何添加的

map_view 插件的依赖添加到pubspec.yaml 如下，然后运行flutter packages get 将它添加到项目中.开发依赖:地图视图:

解决方案

这里是如何在本地修改插件的步骤，我的插件名为:flutter_abc-0.4.1

1. 右键单击包/插件的导入文件名，选择在 Finder 中显示或按住 CMD + 单击该文件名以转到该文件，然后右键单击文件中的任意位置并选择在 Finder 中显示".

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

2. 将整个包文件夹复制到您的应用程序文件夹

   为了方便劫持文件，只需将所有文件复制到您的应用程序文件夹(与pubspec.yaml 相同级别，而不是在lib 文件夹中)，然后重命名版本:

   例如:flutter_abc-0.4.1-hijacking

   现在您可以修改任何想要在本地修复错误的内容.

3. 修改 pubspec.yaml 指向本地包

   打开你的项目 pubspec.yaml将依赖路径更改为，例如:

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

I am developing a Flutter app, and it uses map_view plugin. I want to add new functionalities to the plugin by modifying the source code. How do I find the actual source code of the plugin in my project after installing it through Flutter?

How plugin is added in Flutter

The dependency for map_view plugin is added to pubspec.yaml as below, then running flutter packages get will add it to the project. dev_dependecies: map_view:

解决方案

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

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".

   Normally it's located at ~/.pub-cache/hosted/pub.darlang.org/flutter_abc-0.4.1

2. Copy whole package folder to your app folder

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

   For example: flutter_abc-0.4.1-hijacking

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

3. Modify pubspec.yaml to point to local package

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

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