AgPage<T> class

Composes a page (or a section of one) from an AgBaseController's AgPageState.

Every state except success has an AG default and may be independently overridden — supplying only errorBuilder, for example, does not require also supplying loadingBuilder or emptyBuilder.

Constructors

AgPage({required AgBaseController<T> controller, required Widget builder(BuildContext context, T data), Key? key, WidgetBuilder? loadingBuilder, Widget errorBuilder(BuildContext context, Object error, StackTrace? stackTrace, VoidCallback retry)?, WidgetBuilder? emptyBuilder, Future<void> onRefresh()?})

const

Properties

builder → Widget Function(BuildContext context, T data)

Builds the success-state content. The only required slot — AG has no sensible default for "your actual screen content".

final

controller → AgBaseController<T>

The controller driving this page's state.

final

emptyBuilder → WidgetBuilder?

Overrides the default AgEmpty. Null = AG default.

final

errorBuilder → Widget Function(BuildContext context, Object error, StackTrace? stackTrace, VoidCallback retry)?

Overrides the default AgError. Null = AG default.

final

hashCode → int

The hash code for this object.

no setter, inherited

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

loadingBuilder → WidgetBuilder?

Overrides the default AgLoading. Null = AG default.

final

onRefresh → Future<void> Function()?

When supplied, wraps success content in a RefreshIndicator that calls this on pull-to-refresh.

final

runtimeType → Type

A representation of the runtime type of the object.
