You can very quickly change your phone theme. The same can be done in the launch_background.xml in the drawable-night (dark theme) folder, replacing with for a black background.ĭo note that the images must be inside of the drawable and drawable-night folders being used respectively. The launch_background.xml in the drawable (light theme) folder can be structured as so, to display an image with a white background: It will automatically change based on Android's system theme. Duplicate this folder and call the second one drawable-night and configure the dark theme style.

In your project folder's android/app/src/main/res there should be a drawable folder, which contains the launch_background.xml for light theme.
