如何在Firebase中托管flutter应用？

Question

What is the freshest instruction on how to host a flutter web app? I am following https://developer.school/tutorials/hosting-a-flutter-web-project-on-firebase-hosting on Windows, and the step firebase init here fails for me.

Here is the content of firebase-debug.log:

You're about to initialize a Firebase project in this directory:

  C:\Coding Repository\230102 flutter hello world\flutter_hello_world

Before we get started, keep in mind:

  * You are currently outside your home directory

Answer 1

The error message says:

project_id must be at most 30 characters long

So it sounds like you entered a project ID that was longer than that.
