From Flutters FAQ

flutter.dev/docs/resources/faq#what-devices-and-os-versions-does-flutter-run-on

Mobile operating systems: Android Jelly Bean, v16, 4.1.x or newer, and iOS 8 or newer.

Mobile hardware: iOS devices (iPhone 4S or newer) and ARM Android devices.

Note Flutter currently does not support building for x86 Android (issue #9253) directly, however apps built for ARMv7 or ARM64 run fine (via ARM emulation) on many x86 Android devices.

We support developing Flutter apps with Android and iOS devices, as well as with Android emulators and the iOS simulator.

We test on a variety of low-end to high-end phones but we don’t yet have an official device compatibility guarantee.

We believe Flutter works well on tablets. We do not currently implement all of the tablet-specific adaptations recommended by Material Design, though we are planning further investment in this area
