Flutter markdown package dependency did not install correctly for me

Question

I wan to use flutter markdown package, but I can't. I added dependency (in pubspec.yaml):

dependencies:
  flutter_markdown: "^0.0.9"

After I upgraded package and dependency, but when I used

import 'package:flutter_markdown/flutter_markdown.dart';

statement I got error message URI doesn't exist. I upgraded flutter and tried again, but nothing. I tried adding another way:

dependencies:
  flutter_markdown:
    git: "https://github.com/flutter/flutter_markdown.git"

But result is the same.

How can I solve this problem?

(I use other packages without problem.)

Solution

I solved this thanks to @raju-bitter comment. Steps:

• Close your IDE (Android Studio/Intellij Idea/etc)

• Remove the cache directory (My was located at C:\Users\Username\AppData\Roaming\Pub)

• Reopen your IDE.

If you still get an error then execute flutter package get in your terminal or from IDE menu.

Have you tried restarting Intellij?

Adding a dependency on flutter_markdown: "^0.0.9" as you've shown worked fine for me. Can you show a screenshot of the error message you're encountering?

Yes I tried restarting.

I had a similar experience yesterday with another package. After completely removing the ~/.pub-cache folder, restarting IntelliJ, and running flutter package get again it worked.

[raju-bitter]

Do you see the Dart package in the list of External Libraries - Dart Packages inside IntelliJ? And can you see the package folder inside your .pub-cache folder, e.g. ~/.pub-cache/hosted/pub.dartlang.org/flutter_markdown-0.0.9/‌​?

[Günter Zöchbauer]

Removing ~/.pub-cache is a bit radical. I'd try that last and also try running pub cache repair first.

[raju-bitter]

Tried that, but didn't solve my problem.

Did you run flutter packages get on the command line, after you added the dependency to your pubspec.yaml ?
