flutter run -v showed that I was stuck on

Downloading https://services.gradle.org/distributions/gradle-5.6.2-all.zip

This was going to take hours, as for some reason the download speed was ~10kB/s on a decent DSL connection.

Solution:

1. Interrupt gradle build
2. Download the required gradle zip from a fast mirror: https://distfiles.macports.org/gradle/gradle-5.6.2-all.zip
3. Copy gradle-5.6.2-all.zip to C:\Users\ \.gradle\wrapper\dists\gradle-5.6.2-all\9st6wgf78h16so49nn74lgtbb (of course the last folder will have a different name on your PC)
4. flutter run and voilà.
