startAt abstract method

Query startAt(
  1. dynamic value, {
  2. String? key,
})

Creates a Query with the specified starting point. The generated Query includes children which match the specified starting point. If no arguments are provided, the starting point will be the beginning of the data.

The starting point is inclusive, so children with exactly the specified priority will be included. Though if the optional name is specified, then the children that have exactly the specified priority must also have a name greater than or equal to the specified name.

startAt() can be combined with endAt() or limitToFirst() or limitToLast() to create further restrictive queries.

Implementation

Query startAt(dynamic value, {String? key});
