value<T> static method
Order elements by their value before filtering them.
When using the orderBy="$value"
parameter to sort your data, children
will be ordered by their value. The ordering criteria is the same as data
ordered by a child key, except the value of the node is used instead of
the value of a specified child key.
Implementation
static FilterBuilder<T> value<T>() => FilterBuilder<T>._(r'$value');
