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_command
package.
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
