Row class final
A single row in the result of a select statement.
This class implements the Map interface, which can be used to look up the value of a column by its name. The columnAt method may be used to obtain the value of a column by its index.

newEntries
to this map.inherited -
cast<
RK, RV> () → Map< RK, RV> -
Provides a view of this map as having
RK
keys andRV
instances, if necessary.inherited -
clear(
) → void -
Throws an UnsupportedError;

value
.inherited -
forEach(
void action(String key, dynamic value)) → void -
Applies
action
to each key/value pair of the map.inherited -
map<
K2, V2> (MapEntry< K2, V2> transform(String key, dynamic value)) → Map<K2, V2> -
Returns a new map where all entries of this map are transformed by
the given
convert
function.inherited -
