I am having this problem when I try to compile my first app in flutter. I have already read several solution proposals but they are for mac or linux, when I try to use the command: chmod a + rx android / gradlew
it tells me it does not exist. I am using windows. I attach photos of the error error flutter doctor
From the screenshot given the problem seems to be with where your project is located. Try moving your project into an accessible folder/ directory outside of the the C:/ or the current directory into something like C:/users/your_username/fluter_development/. This will make sure that gradle has the right permissions to download the necessary artifacts to build your app successfully.
