Animated theme switcher.
This library starts from Peyman's stackoverflow question how-to-add-animation-for-theme-switching-in-flutter
Add animated_theme_switcher: "^2.0.8" in your pubspec.yaml dependencies.
dependencies:
animated_theme_switcher: "^2.0.8"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,
isReversed: false // default: false
);
...
},
);Alternatively you could use ThemeSwitcher.switcher() or ThemeSwitcher.withTheme().
Builders of this constructors already provide you ThemeSwitcher.
ThemeSwitcher.withTheme() also provides current theme:
ThemeSwitcher.switcher(
builder: (context, switcher) {
...
onTap: () => switcher.changeTheme(
theme: newTheme,
);
...
},
);
ThemeSwitcher.withTheme(
builder: (context, switcher, theme) {
...
onTap: () => switcher.changeTheme(
theme: theme.brightness == Brightness.light
? darkTheme
: lightTheme,
);
...
},
);Use optional named parameter clipper to pass the custom clippers.
...
ThemeSwitcher(
clipper: ThemeSwitcherBoxClipper(),
builder: (context) {
...
},
);Notes:
-
This package is not intended to persist selected theme on the local device. But we added special example to show how to do it using shared_preferences package.
-
Use the CanvasKit rendering engine to use it on web, more about it..
