ZeroApp class

An application that uses zero-ui design.

A convenience widget that wraps a number of widgets that are commonly required for zero-ui design applications. It builds upon a WidgetsApp by adding zero-ui-design specific functionality, such as AnimatedFluentTheme.

The ZeroApp configures the top-level Navigator to search for routes in the following order:

  1. For the / route, the home property, if non-null, is used.

  2. Otherwise, the routes table is used, if it has an entry for the route.

  3. Otherwise, onGenerateRoute is called, if provided. It should return a non-null value for any valid route not handled by home and routes.

  4. Finally if all else fails onUnknownRoute is called.

If a Navigator is created, at least one of these options must handle the / route, since it is used when an invalid initialRoute is specified on startup (e.g. by another application launching this one with an intent on Android; see dart:ui.PlatformDispatcher.defaultRouteName).

This widget also configures the observer of the top-level Navigator (if any) to perform Hero animations.

If home, routes, onGenerateRoute, and onUnknownRoute are all null, and builder is not null, then no Navigator is created.

See also:

  • NavigationView, to provide zero-ui app-wide navigation
  • Navigator, which is used to manage the app's stack of pages.
  • WidgetsApp, which defines the basic app elements but does not depend on the zero-ui library.

Creates a ZeroApp that uses the Router instead of a Navigator.

Properties

actions → Map<Type, Action<Intent>>?
The default map of intent keys to actions for the application.
final
backButtonDispatcher → BackButtonDispatcher?
A delegate that decide whether to handle the Android back button intent.
final
builder → TransitionBuilder?
A builder for inserting widgets above the Navigator or - when the WidgetsApp.router constructor is used - above the Router but below the other widgets created by the WidgetsApp widget, or for replacing the Navigator/Router entirely.
final
checkerboardOffscreenLayers → bool
Turns on checkerboarding of layers rendered to offscreen bitmaps.
final
checkerboardRasterCacheImages → bool
Turns on checkerboarding of raster cache images.
final
color → Color?
The primary color to use for the application in the operating system interface.
final
darkTheme → ZeroThemeData?
The ThemeData to use when a 'dark mode' is requested by the system.
final
debugShowCheckedModeBanner → bool
Turns on a little "DEBUG" banner in debug mode to indicate that the app is in debug mode. This is on by default (in debug mode), to turn it off, set the constructor argument to false. In release mode this has no effect.
final
hashCode → int
The hash code for this object.
no setterinherited
home → Widget?
The widget for the default route of the app (Navigator.defaultRouteName, which is /).
final
initialRoute → String?
The name of the first route to show, if a Navigator is built.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
locale → Locale?
The initial locale for this app's Localizations widget is based on this value.
final
localeListResolutionCallback → LocaleListResolutionCallback?
This callback is responsible for choosing the app's locale when the app is started, and when the user changes the device's locale.
final
localeResolutionCallback → LocaleResolutionCallback?
The signature of WidgetsApp.localeResolutionCallback.
final
localizationsDelegates → Iterable<LocalizationsDelegate>?
The delegates for this app's Localizations widget.
final
A key to use when building the Navigator.
final
The list of observers for the Navigator created for this app.
final
onGenerateInitialRoutes → InitialRouteListFactory?
The routes generator callback used for generating initial routes if initialRoute is provided.
final
onGenerateRoute → RouteFactory?
The route generator callback used when the app is navigated to a named route.
final
onGenerateTitle → GenerateAppTitle?
If non-null this callback function is called to produce the app's title string, otherwise title is used.
final
onUnknownRoute → RouteFactory?
Called when onGenerateRoute fails to generate a route, except for the initialRoute.
final
restorationScopeId → String?
The identifier to use for state restoration of this app.
final
routeInformationParser → RouteInformationParser<Object>?
A delegate to parse the route information from the routeInformationProvider into a generic data type to be processed by the routerDelegate at a later stage.
final
routeInformationProvider → RouteInformationProvider?
A object that provides route information through the RouteInformationProvider.value and notifies its listener when its value changes.
final
routerConfig → RouterConfig<Object>?
An object to configure the underlying Router.
final
routerDelegate → RouterDelegate<Object>?
