animated_theme_switcher

Animated theme switcher.

This library starts from Peyman’s stackoverflow question how-to-add-animation-for-theme-switching-in-flutter

Getting started

Add animated_theme_switcher: “^2.0.1” in your pubspec.yaml dependencies.

dependencies:
 animated_theme_switcher: "^2.0.1"

How To Use

Import the following package in your dart file

import 'package:animated_theme_switcher/animated_theme_switcher.dart';

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) {
        ...
      },
    );
