Visual Studio Code - Target of URI doesn t exist package flutter material dart

Question

I ve just setup my Macbook for flutter development    So I downloaded flutter sdk  and placed it in my Documents  After  I setup my path variable to work with flutter in my command line   I execute the command flutter create todolist so I achieve a blank project   I also setup my visual studio code with Dart-Code so I have the proper syntax highlight  intellisense  etc   So when I open visual studio code  it highlights the import method  like the following image     This means that it also highlights the classes that are correct  making it completely hard to understand if its a real error or not   I have executed both pub get and flutter packages get and got everything correctly  I have my path variables all correctly   Why is it highlighting it cannot find that  import  package

Author of the Dart Code plugin here  From the screenshot  I would say this is because your flutter project is in a sub-folder of the folder open in Code  We only scan the opened-folder to check whether it s a Flutter project - which then changes the SDK we launch and also enables the Flutter functionality  like the daemon and debugger    You should re-open the  todo  folder directly   If you want to have multiple projects open together  use multi-root workspaces  since Dart Code is multi-root-aware and will check each of the folders in the workspace when deciding if it needs to enable Flutter functionality   Update  This case should be better supported in the Dart plugin now  so opening the immediate parent folder of a Flutter project should work as expected

Warning  This package referenced a Flutter repository via the    packages file that is no longer available  The repository from which   the  flutter  tool is currently executing will be used instead    running Flutter tool   opt flutter   previous reference       Users Shared Library flutter This can happen if you deleted or moved   your copy of the Flutter repository  or if it was on a volume that is   no longer mounted or has been mounted at a different location  Please   check your system path to verify that you are running the expected   version  run  flutter --version  to see which flutter is on your   path     Checking the output of the flutter packages get reveals that the reason in my case was due to moving the flutter sdk

When you usually get this error message      Target of URI doesn t exist   package foo   Try creating the file   referenced by the URI  or Try using a URI for a file that does exist    Example      Target of URI doesn t exist     package random string random string dart   Try creating the file   referenced by the URI  or Try using a URI for a file that does exist    import  package random string random string dart     It is because a dependency is missing    So all you have to do is find out what packages are needed by googling your package name     Install the dependency     flutter pub get   and add the dependency in the pubspec yaml file

I also had this issue  I had both VS code and Android studio installed in my system  The error was in VS code  When i opened the same project on Android studio  the dependency was not actually added to pubsec yaml  I added it there and ran pub get  When I returned to VS Code and everything was working fine  So  Try opening it in other editor if you have  or through NotePad  Edit  Opening widget test dart and running it should also solve your issue

Simple thing I did after Someone said here to restart the VSCode and I did that  and now everything works fine  For me it was because just when I was creating project I got an notification for updating my dart or related  extension and for that I did it and boom as my project started  it just gave me around 30 errors which do scared but the simple FIX was to RESTART THE EDITOR

I was using  goggle location picker  with much more customisation in functions and UI    so I copy this package complete  and using in my app in one folder but since dart code analyser analyses one flutter project so I found that those which are referencing from inside of this package is not working then I copy only lib folder of google location picker  in my original project folder and voila this worked for me  This solution took me a time of 3 days  I know this is not the question but it might help someone to save 3 days

Don t forget to save pubspec yaml before running  flutter pub get   Restarting Visual Studio Code is not enough  That was my solution  Sometimes when you work with intellij you forget that

Basically  Check for correct indentation of your package in dependencies if your editor supports  it automatically runs - gt  flutter pub get Either way - gt  open terminal- gt  flutter pub get or flutter packages get check  packages file  see if your package is present else reinstall package Most important   Restart your IDE  Visual studio or Android Studio   Start debugging your project Most probably   your errors will be fixed by then Hope it works for you

Close the VS Code and Run it again

User · Answer

Sometimes  this issue is resolved simply by running flutter pub get once again    packages get to make sure that all packages are considered    as when moving the project from one computer to another  this may happen  that the packages are not taken into consideration  so flutter pub get and there you go

User · Answer

Add dependencies  for example - import  package audioplayers audio cache dart   in the above package if we only use this package then it shows error  but if we add dependencies in pubspec yaml  such as   dependencies      flutter        sdk  flutter     cupertino icons   0 1 2     audioplayers   0 14 1     then click on packages get   as you see this  I can also insert dependencies so if you insert dependencies along with your package then you are good to go
