When is it appropriate to use packages, plugins or third-party dependencies?

Posted by Jennifer | Updated on

Packages and plugins are great for saving you time and work. There’s no need to solve a complex problem yourself when someone else has done it already, especially if the solution is highly rated.

On the other hand, there’s also a danger of being too reliant on third party packages. They can break, have bugs or even be abandoned. When you need to switch to a new package down the road, you might have to make huge changes to your code.

That’s why it’s important to isolate packages from your core business logic. You can do that by creating an abstract Dart class that acts as an interface for the package. Once you’ve set up that kind of architecture, all you have to do to switch packages is to rewrite the concrete wrapper class that implements your interface.
