Not sure what Android convention is, but personally bitwise operations read a lot clearer to me using hex literals.

Is View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR not available?

Not until we update our target SDK

…system_chrome

I've updated this PR based on offline discussion with @Hixie and @HansMuller.

Instead of just extending the dark and light theme to Android, we should allow users to customize all of the different system chrome related APIs. This PR works in tandem with https://github.com/flutter/flutter/pull/17171/files to extend the systemOverlayStyle with multiple values for the different parts of each platforms system chrome.

Currently on Android, versions less than 26 are not allowed to customize these settings from flutter since there are no "light" settings for the status or nav bar icons.

As a part of a later process, we'll remove the SystemChrome api calls from the app bar widgets and instead specify a theme-like way to customize system chrome. This is only intended to be a low-level API

LGTM

+                        if ((flags & 0x10) == 0) {


This test and the similar tests below don't seem necessary?

My bit-fu is weak, but I believe this is necessary because we currently can set the same system chrome flag multiple times. If it is already on/off we don't want to toggle it again.

But x |= 0x10 doesn't toggle the bit, it just ensures that it's set. 0x10 | 0x10 == 0 | 0x10

Right, fixed

…and rename fields

Since this will require an engine roll and and a separate framework PR i'm going to wait until tomorrow when the build is hopefully green

Sorry for not bringing this up earlier. To unconditionally turn a bit off:

flags &= ~0x10;
