ApiCallBuilder<T extends Decodable, E extends Decodable> class
This widget helps to manage transparently an API call in the widget tree
showing a loading widget while performing the request and providing access
to the response in the builder
parameter, to show a proper widget on http call completion.
It must be used with the ConnectionManager, that is what manages API call and states through a bloc component.
T
and E
are, respectively, the class to decode in the success response and the
class to decode for an error response.
If not provided, the builder will have a generic Object as argument, that then
should be casted to use.

Properties
-
apiCall
→ APIRequest<
T, E> -
The api call to perform with the ConnectionManager. It is the same apicall
with
doApiRequest
that is normally performmed by the ConnectionManagerfinal -
builder
→ Widget Function(BuildContext context, T? response, List<
T> ? responseList) -
The builder for a widget when the API call is successfull.
The
response
argument is the class decoded by the ConnectionManager. TheresponseList
argument is the class decoded as a list.final - child → Widget Function(Widget child)?
-
Optionally, you can specify a Widget to not be involved in api calls rebuild
final
- errorBuilder → Widget Function(BuildContext context, String? errorMessage)?
-
Optionally, a widget to manage the error state can be provided. The
errorMessage
argument is the error retrieved by the API call (if any). If not provided, a default error text is shown.final - hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- loaderBuilder → Widget Function(BuildContext context)?
-
Optionally, a widget for the loading state can be provided. If null, a default
black loading spinner is shown.
