flutter 项目中的根文件（main.dart）在哪里？

Question

I just bought a flutter UI from online. Now I couldn't find the root file where all the package and classes imported.

Is there any solution to find the root class?

If you have purchased a commercial Flutter Widget, then usually the documentation will ask you to add an entry to the pubspec.yaml file. After that flutter will download the dependencies and will merge them with your project.

All you have to do is to reference the package in your source code through a simple import function.

Take a look at an example here: https://pub.dev/packages/mobx/install

You add a pubspec entry, save, your IDE will download the dependencies, then import the package into your source code.
