What needs to use Dispose in Flutter?

UPDATE: I have a general idea of what dispose does. But I want a list of specific items have to be disposed, like: text controllers, stream controllers, or "any and all variables declared in a Stateful page"...

Here is the original post:
...
I know you use Dispose to "clean up" a Stateful page. And I have used it for textfield controllers. But I am unclear on:

  1. what types of things need to be disposed? (besides textfield controllers)
  2. what happens if you don't dispose? (memory leaks?)

Thanks!

dispose method is used to release the memory allocated to variables when the state object is removed.

For example, if you are using a stream in your application then you have to release memory allocated to the stream controller. Otherwise, your app may get a warning from the PlayStore and AppStore about memory leakage.
