JDK is not valid

I am getting the following message after I connect the firebase...
I have installed JDK version 14.0.1 but it still looking for a jdk inside the jre directory.

Launching lib\main.dart on ONEPLUS A5000 in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

• What went wrong:
