kotlin observable example

Create a variable of type Observable using the Observable.create method.

Within the create method, define the onSubscribe function which takes an Emitter as a parameter.

Inside the onSubscribe function, call the onNext method of the Emitter to emit a value.

After emitting the value, call the onComplete method of the Emitter to indicate that the emission is complete.

Outside the onSubscribe function, return a lambda that will be called when the Observable is disposed.

Subscribe to the Observable and provide onNext and onComplete functions to handle the emitted value and completion event.
