Can't change mainOverlay opacity in tweenHandler

See original GitHub issue

I want the main content to go dark when the drawer is open by setting the mainOverlay background to black and opacity to 0 and in tweenHandler tried to change the opacity but it doesn’t seem to work:

<Drawer
        ref="navigation"
        type="displace"
        content={<SideMenu />}
        tapToClose={true}
        openDrawerOffset={0.2}
        panCloseMask={0.2}
        styles={{mainOverlay: {backgroundColor: '#000000', opacity: 0}}}
        negotiatePan={true}
        tweenHandler={(ratio) => ({
          mainOverlay: { opacity: ( ratio / 2 )}
        })}
      >

Is this a bug or am I doing it wrong?

Thanks.

Don’t know if anyone is still needing help, but I figured out how to make the area behind the drawer go darker with opacity.

tweenHandler={(ratio) => ({ mainOverlay:{ backgroundColor:"rgba(71, 71, 71,"+ (ratio)/1.5+")"}, })}

I just used rgba (which is supported by react native. Runs on both iOS and Android) and used the ratio to control the opacity. Hope that helps! @rt2zz @Qizly
