-- Returns a list of the dashboards for your account. If you include
-- @DashboardNamePrefix@, only those dashboards with names starting with
-- the prefix are listed. Otherwise, all dashboards in your account are
-- listed.
--
-- @ListDashboards@ returns up to 1000 results on one page. If there are
-- more than 1000 dashboards, you can call @ListDashboards@ again and
-- include the value you received for @NextToken@ in the first call, to
-- receive the next 1000 results.
--
-- This operation returns paginated results.
