And my code :

var _locationService = new Location();

bool serviceStatus = await _locationService.serviceEnabled();

Your flutter doctor suggests that flutter is not properly configured on neither of the IDEs. Can you find those plugins under Project structure -> External Libraries -> Flutter Plugins. If not, please do flutter packages get — Vamsi
@Vamsi yes ,i can find all plugins under External Libraries i think it's not about Flutter version because i do create a new project and i test one of those Libraries and everything was OK, maybe its plugin dependence or IDK — Mahmoud Sabri
I agree with @Vamsi. With this instances, first thing you can do is flutter clean and flutter packages get. Same as what happened in this GitHub post. To further understand your issue, could you provide a minimal, complete and verifiable example? — MαπμQμαπkγVπ.0

Have you tried running a restart after adding the plugin? Running the app using hot reload may have yet to include the plugin that you've recently added on your build.
