Hi Francois!
Not stupid at all 😉
The AppTabBar uses the colors from the app Theme, see here for a list of available configurations.
To change theme settings, simply use the onInitTheme signal of the app:
App {
onInitTheme: {
Theme.tabBar.backgroundColor = "green"
}
}
The default value uses the configured Theme.colors.tintColor, so you can also change the tint-color in case you also want the same color for e.g. buttons or the navigation bar.
Cheers,
Günther
