useTheme function need more explanation

[adrianrz]

When try to use this example in my project

export type AppTheme = typeof myTheme; export const useAppTheme = () => useTheme<AppTheme>();

This not overwrite defaultTheme with myTheme, I investigate the source code of useTheme and I discover that have a theme parameter that not is in the example:

export const useAppTheme = () => useTheme<AppTheme>(myTheme);
