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.

Methods

addAll(Map<String, dynamic> other) → void
Adds all key/value pairs of other to this map.
inherited
addEntries(Iterable<MapEntry<String, dynamic>> newEntries) → void
Adds all key/value pairs of newEntries to this map.
inherited
cast<RK, RV>() → Map<RK, RV>
Provides a view of this map as having RK keys and RV instances, if necessary.
inherited
clear() → void
Throws an UnsupportedError; operations that change the map are disallowed.
inherited
columnAt(int i) → dynamic
Returns the value stored in the i-th column in this row (zero-indexed).
containsKey(Object? key) → bool
Whether this map contains the given key.
inherited
containsValue(Object? value) → bool
Whether this map contains the given 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
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent(String key, dynamic ifAbsent()) → dynamic
Look up the value of key, or add a new entry if it isn't there.
inherited
remove(Object? key) → dynamic
Throws an UnsupportedError; operations that change the map are disallowed.
inherited
removeWhere(bool test(String key, dynamic value)) → void
Removes all entries of this map that satisfy the given test.
inherited
toString() → String
A string representation of this object.
inherited
toTableColumnMap() → Map<String?, Map<String, dynamic>>?
Returns a two-level map that on the first level contains the resolved non-aliased table name, and on the second level the column name (or its alias).
update(String key, dynamic update(dynamic value), {dynamic ifAbsent()?}) → dynamic
Updates the value for the provided key.
inherited
updateAll(dynamic update(String key, dynamic value)) → void
Updates all values.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited
operator [](Object? key) → dynamic
The value for the given key, or null if key is not in the map.
override
operator []=(String key, dynamic value) → void
Throws an UnsupportedError; operations that change the map are disallowed.
