Null safety
An EmpireProperty with similar characteristics as a dart Map<K, V>
Any change to the internal map will send a EmpireStateChanged event by default. This includes automatically triggering a UI rebuild.

add(
K key, V value, {bool notifyChanges = true}) → void -
If the
keyis already in this map, the corresponding value is overwritten. -
addAll(
Map< K, V> other, {bool notifyChanges = true}) → void -
Adds all key/value pairs of
otherto this map. -
addEntries(
Iterable< MapEntry< entries, {bool notifyChanges = true}) → voidK, V> > -
Adds all key/value pairs of
newEntriesto this map. -
addEntry(
MapEntry< K, V> entry, {bool notifyChanges = true}) → void - Adds the key/value pair to this map.
-
call(
Map< K, V> value, {bool notifyChange = true}) → void -
inherited
-
clear(
{bool notifyChanges = true}) → void - Removes all entries from the map.

value. -
equals(
dynamic other) → bool -
Checks if
otheris equal to the value of this EmpirePropertyinherited -
forEach(
void action(dynamic, dynamic)) → void -

actionto each key/value pair of the map. -
map<
K2, V2> (MapEntry< K2, V2> convert(dynamic, dynamic)) → Map<K2, V2> -
