how to use

import the following package in your dart file

wrap materialapp with themeprovider widget, as it has shown in the following example:

  themeprovider(
      inittheme: inittheme,
      builder: (context, mytheme) {
        return materialapp(
          title: 'flutter demo',
          theme: mytheme,
          home: myhomepage(),
        );
      }),
    ),

but if all you want is to provide a theme, use as follows:

  themeprovider(
      inittheme: inittheme,
      child: somecoolpage(),
    ),

wrap the screen where you whant to make them switch with themeswitchingarea widget, as it has shown in the following example:

    themeswitchingarea(
      child: builder(builder: (context) {
        return ...,
      },
    );

wrap every switcher with themeswitcher builder, and use themeswitcher.of(context).changetheme function to switch themes;

    themedata newtheme = themedata(
      primarycolor: colors.amber
    );
    ...
    themeswitcher(
      builder: (context) {
        ...
        ontap: () => themeswitcher.of(context).changetheme(
          theme: newtheme,
          reverseanimation: false // default: false 
        );
        ...
      },
    );

use optional named parameter clipper to pass the custom clippers.

    ...
    themeswitcher(
      clipper: themeswitcherboxclipper(),
      builder: (context) {
        ...
      },
    );

use optional named parameter clipper to pass the custom clippers.

    ...
    themeswitcher(
      clipper: themeswitcherboxclipper(),
      builder: (context) {
        ...
      },
    );
