Record class

A Record is structured using a Map structure.

The Map keys are of the type int and the values are CandidTypes. It is possible to use a String for the field-name when setting a field or looking up a value, however the String field-name gets converted into an int using the candid_text_hash according to the candid-specification. So when iterating through the keys/field-names of the Record the key is an int type. Use the candid_text_hash function to get the int representation of a String field-name. Creating a Record.

var record = Record.of_the_map({
    'greeting': Text('Hi'),
    'name': Text('Bob'),
    'address_info': Record.of_the_map({
        'zip_code': Nat(12345),
        'street_name': Text('Mountain'),
    }),
    'ready': Bool(true)
});

var tuple_style_record = Record.of_the_map({
    0: Nat(5),
    1: Text('green')
});

Methods

addAll(Map<int, CandidType> other) → void: Adds all key/value pairs of other to this map.
inherited
addEntries(Iterable<MapEntry<int, CandidType>> 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: Removes all entries from the map.
inherited
containsKey(dynamic key) → bool: Whether this map contains the given key.
inherited
containsValue(Object? value) → bool: Whether this map contains the given value.
inherited
find_option<T extends CandidType>(dynamic key) → T?: Candid subtyping rules state that an Option can be missing within a record if it is sent with a null-value. Use this function when looking for an Option in a Record. key can be a String or an int.
forEach(void action(int key, CandidType value)) → void: Applies action to each key/value pair of the map.
inherited
map<K2, V2>(MapEntry<K2, V2> transform(int key, CandidType 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(int key, CandidType ifAbsent()) → CandidType: Look up the value of key, or add a new entry if it isn't there.
inherited
remove(Object? key) → CandidType?: Removes key and its associated value, if present, from the map.
inherited
removeWhere(bool test(int key, CandidType value)) → void: Removes all entries of this map that satisfy the given test.
inherited
toString() → String: A string representation of this object.
inherited
update(int key, CandidType update(CandidType value), {CandidType ifAbsent()?}) → CandidType: Updates the value for the provided key.
inherited
updateAll(CandidType update(int key, CandidType value)) → void: Updates all values.
inherited

Operators

operator ==(Object other) → bool: The equality operator.
inherited
operator [](dynamic key) → CandidType?: The value for the given key, or null if key is not in the map.
inherited
operator []=(dynamic key, CandidType value) → void: Associates the key with the given value.
