RxCommandBuilder<T, R> class

Spinner/Busy indicator that reacts on the output of a Stream<CommandResult<dynamic, R>>. 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, no data, error) that can be emitted it offers three option Builder methods.

Constructors

RxCommandBuilder({Key? key, required Stream<CommandResult<T, R>> commandResults, TargetPlatform? platform, BusyBuilder? busyBuilder, RxBuilder<R>? dataBuilder, PlaceHolderBuilder? placeHolderBuilder, ErrorBuilder<CommandError<T>>? errorBuilder})
Creates a new RxCommandBuilder instance commandResults : Stream<CommandResult<dynamic, R>> or a RxCommand<dynamic, R> 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 field 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 field of the CommandResult. If this is null a Container will be created instead.
