✔ Select a Firebase project to configure your Flutter application with · <create a new project> 

✔ Enter a project id for your new Firebase project (e.g. my-cool-project) · first-trial-proj 

i New Firebase project first-trial-proj created succesfully.

FirebaseCommandException: An error occured on the Firebase CLI when attempting to run a command.

COMMAND: firebase projects:create first-trial-proj --json

ERROR: Failed to create project because there is already a project with ID first-trial-proj. Please try again with a unique project ID-----

This is what happens when I try to create a firebase project. Also I don't know why it accepted "in-demo-proj" as the name.

CodePudding user response：

Project names in Firebase and Google Cloud have to be globally unique amongst all users. The error message seems to indicate that a project named first-trial-proj already exists.

You might want to try something a but more likely to be unique, like a combination of your name and the date.

Alternatively, you can first create the project in the Firebase console (which performs such checks for uniqueness as you type) and only then run the FlutterFire CLI and select the project.
