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({Stream<CommandResult<T>> commandResults, TargetPlatform platform, double radius: 20.0, Color backgroundColor, double value, Animation<Color> valueColor, double strokeWidth: 4.0, BuilderFunction<T> dataBuilder, Builder placeHolderBuilder, BuilderFunction<Exception> errorBuilder, Key key })
Creates a new RxLoader instance busyEvents : Stream<bool> that controls the activity of the Spinner. On receiving true it replaces the normal widget and starts running undtil it receives a falsevalue. 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. all other parameters please see https://docs.flutter.io/flutter/material/CircularProgressIndicator-class.html they are ignored if the platform style is iOS.
