Very simple app development ( flutter )

Job ID: 36370704

Budget: $10 – $30 USD

So I need a very simple app developed in flutter.
1) It will track all incoming and outgoing calls.
2) When call ends it will send the phone number and duration to an api endpoint.
a) If the api response is false, it will do nothing.
b) If the api response is true and returns a name, it will show a floating popup form with a textarea and submit button.
- Clicking the submit button will send the data to an api endpoint with success message.

That's it.

This is just a test project so i am looking for very reasonable price. Newcomers are also welcome. You will have to provide me flutter code for testing. Code needs to work on both android and iOS.
