It’s possible to conduct unit, widget, and integration testing on a Flutter project, even if it has already been developed and has many dependencies.

Here are some relevant Kodeco articles:

- [Unit Testing With Flutter: Getting Started](https://www.kodeco.com/6926998-unit-testing-with-flutter-getting-started)
- [Widget Testing With Flutter: Getting Started](https://www.kodeco.com/36300023-widget-testing-with-flutter-getting-started)
- [Kodeco article Integration Testing in Flutter: Getting Started](https://www.kodeco.com/29321816-integration-testing-in-flutter-getting-started)

As you have asked for GitHub examples, check out the [flutter-testing-tutorial](https://github.com/bwnyasse/flutter-testing-tutorial) repository. This project provides a thorough example of performing unit, widget, and integration testing in a Flutter application. You can see how they structured their tests and handled dependencies, and you might find it a good reference for setting up tests in your project​. However, the project has not been updated for over two years, so you may find running on current Flutter versions challenging.
