RxCommandBuilder<T> class

Spinner/Busyindicator that reacts on the output of a Stream<CommandResult<T>>. It's made especially to work together with RxCommand from the rx_commandpackage. it starts running as soon as an item with isExecuting==true is received until isExecuting==true is received. To react on other possible states (data, nodata, error) that can be emitted it offers three option Builder methods

Constructors

RxCommandBuilder({Key key, Stream<CommandResult<T>> commandResults, TargetPlatform platform, BuilderFunction1 busyBuilder, BuilderFunction<T> dataBuilder, BuilderFunction1 placeHolderBuilder, BuilderFunction<Exception> errorBuilder })
Creates a new RxCommandBuilder instance commandResults : Stream<CommandResult<T>> or a RxCommand<T> that issues CommandResults busyBuilder : Builder that will be called as soon as an event with isExecuting==true. dataBuilder : Builder that will be called as soon as an event with data is received. It will get passed the data feeld of the CommandResult. If this is null a Container will be created instead. placeHolderBuilder : Builder that will be called as soon as an event with data==null is received. If this is null a Container will be created instead. dataBuilder : Builder that will be called as soon as an event with an error is received. It will get passed the error feeld of the CommandResult. If this is null a Container will be created instead.
