Target of URI doesn't exist 'package:flutter/material.dart'

Question

My Flutter IDE (Android Studio) doesn't recognize material.dart anymore! It happened suddenly, I was working normally then my PC turned off because of CPU 100% consumption and when I restarted I found this problem.

Answer 1

Flutter Issue Fix: 18-April-2020

It happened due to :

1. You have created a project and then you try to push the code to Git ( and keeping your vscode open)
2. Your package needs to update using command flutter packages get ( simply from vscode menu choose terminal and then run this command )
3. If you still it didn't fix your issue, simply go to File Menu, choose Close Folder, it fixes your issue.
4. Last option restart VSCode.

Answer 2

1. ctrl -> Shift -> A (Find Action)
2. Search for "Dart Analysis"
3. Click the icon that says "Restart the Dart Analysis server"
4. The red underline disappears from the package import and everything works.
