Add support for Android host

[Yisus7u7]

Currently, it is possible to compile android apps, for example, in kotlin on an android device without emulating any GNU/Linux system.

I would like to program in flutter from my cell phone, but flutter does not support android on its supported hosts, please, it would be very good to add support to run it on android.

Log:

Flutter crash report.
Please report a bug at https://github.com/flutter/flutter/issues.

I would like to program in flutter from my cell phone

@Yisus7u7 why?
(sounds dramatic, but seriously... what's the use case?)

[Yisus7u7]

@iapicca Simply, apart from the fact that many people without a computer will be able to create apps with flutter from their cell phone, it would give me comfort to use neovim on my cell phone and program in flutter while I do not have my computer available. In any case, it is not difficult.

[darshankawar]

Thanks for the report. Labeling this as a potential proposal.
