view library

This library provides view builders.

Classes

RefreshView

A widget that wraps a widget with a RefreshIndicator designed to be used with BLoC pattern.

ViewStateBuilder<T, B extends BlocBase<ViewState<T>>>

ViewStateBuilder is responsible for building the UI based on the ViewState. It's a wrapper over the BlocBuilder widget so it accepts a bloc object and a set of handy callbacks, which corresponds to each possible state: initial builder for the the initial state, loading builder for the data loading state, refreshing builder for the data refreshing state, data builder for the data state, empty builder for for no result state, error builder function for an error state. buildWhen a condition to determine whether to rebuild the view with the current state

ViewStateListener<T, B extends BlocBase<ViewState<T>>>

ViewStateListener is responsible for performing an action based on the ViewState.

Typedefs

DataBuilder<T> = Widget Function(BuildContext context, T data)

Builder function for a success state. The data was fetched and nonnull element was returned.

DataCallback<T> = void Function(BuildContext context, T data)

Callback function for a success. The data was fetched and nonnull element was returned.

EmptyBuilder = Widget Function(BuildContext context)

Builder function for no result. The data was fetched successfully, but a null element was returned.

EmptyCallback = void Function(BuildContext context)

Callback function for no result. The data was fetched successfully, but a null element was returned.

ErrorBuilder = Widget Function(BuildContext context, Object error)

Builder function for an error. It contains an error that has caused which may allow a view to react differently on different errors.

ErrorCallback = void Function(BuildContext context, Object error)

Callback function for an error. It contains an error that has caused which may allow a view to react differently on different errors.

InitialBuilder = Widget Function(BuildContext context)

Builder function for the the initial state.

LoadingBuilder = Widget Function(BuildContext context)

Builder function for the data loading state.

LoadingCallback = void Function(BuildContext context)

Callback function for the data loading state.

RefreshingBuilder<T> = Widget Function(BuildContext context, T data)

Builder function for the data refreshing state. Can only occur after DataBuilder.

RefreshingCallback<T> = void Function(BuildContext context, T data)

Callback function for the data refreshing state

SuccessBuilder<T> = Widget Function(BuildContext context, T data)

Builder function for a success state. The data was fetched and nonnull element was returned.

SuccessCallback<T> = void Function(BuildContext context, T data)

Callback function for a success. The data was fetched and nonnull element was returned.

ViewStateBuilderCondition<T> = bool Function(ViewState<T> previous, ViewState<T> current)

Signature for the buildWhen function which takes the previous ViewState and the current ViewState and returns a bool which determines whether to rebuild the view with the current state.

ViewStateListenerCondition = bool Function(ViewState previous, ViewState current)

Signature for the listenWhen function which takes the previous ViewState and the current ViewState and is responsible for returning a bool which determines whether or not to call the listener function.
