RxLoader<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

RxLoader({Key key, Key spinnerKey, Stream<CommandResult<T>> commandResults, TargetPlatform platform, double radius: 20.0, Color backgroundColor, double value, Animation<Color> valueColor, double strokeWidth: 4.0, BuilderFunction<T> dataBuilder, BuilderFunction1 placeHolderBuilder, BuilderFunction<Exception> errorBuilder })
Creates a new RxLoader instance commandResults : Stream<CommandResult<T>> or a RxCommand<T> that issues CommandResults platform : defines platorm style of the Spinner. If this is null or not provided the style of the current platform will be used radius : radius of the Spinner
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. spinnerKey Widget key of the Spinner Widget of the RxLoader. This can be usefull if you want to check in UI Tests if the Spinner is visible. all other parameters please see https://docs.flutter.io/flutter/material/CircularProgressIndicator-class.html they are ignored if the platform style is iOS.
