builder property
Updates the widget subtree by providing a latest QueryResponse object to the children.
Each Query instance will rebuild its children twice. First rebuild will be called with this QueryResponse instance:
QueryResponse(
data: null,
loading: true,
error: null,
);
Second rebuild will be called with:
QueryResponse(
data: data, // null if your future throws exception
loading: false,
error: null, // null if your [future] exited successfully
);
Implementation
final Widget Function(
BuildContext context,
QueryResponse<T> response,
) builder;
