I had the same problem and I solved it by following the solution at this link; I use Linux but I believe it will fix your problem regarding the operating system you are using.

Open Android studio > go to SDK manager from more actions > in android SDK option select SDK tools > install android SDK command-line tools(latest) and accept the licence.

It will run and if it still shows some licence is missing type the command given in the cmd and run flutter doctor again after accepting the licence.

If you do not have the JDK software installed or if JAVA_HOME is not set, then Flutter will give this error message. The following tasks provide the information you need to install the JDK software and set JAVA_HOME on UNIX or Windows systems.

Download software from the below-given link. Download here

After a successful installation, you can now check from the command line using the below command.

  • C:\Users\Ainswers>java -version
  • java version "1.8.0_251"
  • Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
  • Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)

Kindly exit flutter console (if it is open) then open it again for fresh restart then try to run flutter doctor again. Hope you will get a green check right now.

Go to SDK Tools in Android studio SDK manager, and check on Android SDK Command-line Tools (Latest) then install it.

Go to SDK manager and click on edit in front of your SDK path then install both versions of the SDK.

And Restart your computer

This will definitely fix the problem.
