get theme and get darkTheme returns the same theme dependend on mode

[bernhardfrenking]

Retrieving the ThemeData with get theme and get darkTheme will return not the expected themes of light theme and dark theme, instead both return the "active" theme.

To Reproduce
Compare AdaptiveTheme.of(context).theme with AdaptiveTheme.of(context).darkTheme;.

Expected behavior
theme returns the light theme and darkTheme returns the dark theme.

Responsible Code
from adaptive_theme.dart, which is cousing this behaviour:

  @override
  ThemeData get theme => preferences.mode.isDark ? _darkTheme : _theme;

  @override
  ThemeData get darkTheme => preferences.mode.isLight ? _theme : _darkTheme;
