Is this really what most people will want? AFAIK flutter and capacitor doesn't do this by default.

[amrbashir]

I don't really know, but I kinda hate the hard coded values.

[amrbashir]

Btw I was going to make it fully transparent but backed out of it because it would look awful without also making the navigation bar also transparent and instead decided to just make it translucent which should work fine in most of cases and blend good enough with the user app by default.

Users can still remove this bit and customize it as they want for their app.

Also I have seen more and more Android apps moving towards transparent status bar (and navigation bar). I have a friend who works in Android native and he has noticed this trend as well.

I added previous stuff because that's the only sensible default that many android dev could agree on.
But that's indeed not the case in many scenarios. I think the best we should do is advise users to edit the theme they prefer.
Therese not such thing for default value and we can't control it.

[amrbashir]

Alright, I just removed all the colors and kept the default. I only added the change to hide the action bar.

Transparent navigation bar looks amazing, but I think it might also impact the app more (last time I wrote a native Android app I took me ages to get it perfect).

[amrbashir]

Yeah, I think it will either be a good community plugin or we could just link to a documentation or something and users implement it if they needed it
