The flutter tools aren't launching when I press the button on Android Studio, and I also get a warning when I use flutter run.
I've tried flutter clean, but this still happens on both the terminal and Android Studio flutter plugin.

Rebooting my computer fixed it.
I've recently updated Flutter to 1.25.0-8.1.pre in beta. I could run debug apk and build release. But, the release-apk doesn't work and it stuck on default splash screen. Where the problem lies in. Is there any such bug from Flutter?

If you are using android studio you can click on Tools->SDK Manager, Select the version you need and hit apply/OK.
