I have facing the above issue while Get dependencies .

pubspec.yaml

dev_dependencies:
test: ^0.12.0
http: "^0.11.3+16"
image: "^1.1.30"

Error message

Running "flutter packages get" in dart_demo...

This means that the formatting (indentation) of the content in your pubspec.yaml is invalid.

You'd need to post the content of pubspec.yaml wrapped in ``` for anybody to be able to provide advice.

I'm not getting . I'm new for Dart lang. pls find pubspec.yaml below

name: dart_demo
description: A sample command-line application.
version: 0.0.1

environment:
  sdk: '>=1.20.1 <2.0.0'

dev_dependencies:
  test: ^0.12.0
  http: "^0.11.3+16"
  image: "^1.1.30"

I can't see a problem. Can you please attach the whole file?

[kevmoo]

@nex3 – see anything obvious?

[nex3]

That pubspec works fine for me.

[kevmoo]

Maybe mixing tabs and spaces?

@zoechi @gowsikraja Could you fix it?? I am facing similar issue in my project too, if yes then please help me with it - https://github.com/AgrawalAnsh22/startup_namer/issues

@AgrawalAnsh22 try http://www.yamllint.com or one of https://www.google.at/search?q=validate+yaml&oq=yvalidate+yam&aqs=chrome.1.69i57j0l3.8001j0j7&client=ms-android-google&sourceid=chrome-mobile&ie=UTF-8

@zoechi I just tried running the code in the validator, Thanks i got it resolved.

You should give tab instead of spaces, one tab

[taranjeetsapra]

I found error in pubspec.yaml file of app module of project. You need to add
```
test: ^0.12.0
http: ^0.11.3+16
image: ^1.1.30

to **dev_dependencies** rather than in **dependencies**. Actual code snippet will be:

dev_dependencies:
flutter_test:
sdk: flutter
test: ^0.12.0
http: ^0.11.3+16
image: ^1.1.30
```
Then click on Package get (shown in Android Studio) option to add above dependency for the project. You can also do the same using command(in project stucture):

flutter packages get

I repeatedly read the flutter documentation, but still this error, why?

@O-ID You may try deleting the cache folder inside the bin folder and try again. Also try disabling any antivirus or firewall and try again. That might be it. Good luck
