How to solve "Waiting for a connection from Flutter on device..."

Question

When I run the default test app on my devices all the console outputs is

Waiting for a connection from Flutter on SM N950F...

I thought the problem could be my physical device but I realized this isn't the case I tested it on two emulators and I get the same output.

When I run flutter doctor -v my output is:

Ok, so I've managed to figure something out.- I'll be answering my own question:

My current version of Android Studio (version 4.0.1) just doesn't want to run an app straight from the UI so you kinda have to brute force it from the terminal.

Make sure that your API level you're running your device on is the same as what you have installed on Android Studio.

1.1 Click on the SDK Manager button around the top right corner of AS (The icon is a box with a down arrow next to it)

1.2 Choose the same API level as your device, (When I didn't do this I had a partial install and it took some time to compile), then click apply and wait for it to install.

We're going to run the project to our avd or mobile device from the directory of ourproject.

2.1 Open up the Command Prompt (preferably as Admin), and chage the directoy to where your project is, the command should look something like this

cd Documents\AndroidStudioProjects\your_flutter_app_folder

2.2 Finally type the command flutter run it will take about 1 minute to compile, first time round.
