There should be empty() function

[subhasundardass]

It will be very helpful if there is an empty function at AsyncValue when.

R when({
required R Function(Model) data,
required R Function(Object, StackTrace?) error,
required R Function() loading,

empty ****
})

What exactly is it supposed to do?

[subhasundardass]

if api respond with empty List.
like.. List Cart = []

[rrousselGit]

Why not check that inside data?

ref.watch(provider).when(
  data: (value) {
    if (value.isEmpty) {...}
  }
)

Yes, it can be, but I was looking something like empty function, Like
body: controller.obx(
(state)=>Text(state.name),

    // here you can put your custom loading indicator, but
    // by default would be Center(child:CircularProgressIndicator())
    onLoading: CustomLoadingIndicator(),
    onEmpty: Text('No data found'),

    // here also you can set your own error widget, but by
    // default will be an Center(child:Text(error))
    onError: (error)=>Text(error),
  ),
