TokenIdentifierType class final

TokenIdentifier type for ESDT token identifiers.

Represents ESDT (eStandard Digital Token) identifiers in format TICKER-hexrandom. Does NOT support EGLD native token.

Example

final type = TokenIdentifierType.type;

// From string identifier
final token1 = type.createValue('WEGLD-bd4d79');
final token2 = type.createValue('USDC-c76f1f');

// From bytes
final bytes = 'MYTOKEN-a1b2c3'.codeUnits;
final token3 = type.createValue(bytes);

// Properties
print(token1.ticker); // "WEGLD"
print(token1.randomPart); // "bd4d79"
print(token1.toBytes()); // UTF-8 encoded bytes

// These throw: invalid format
// final invalid1 = type.createValue('EGLD'); // Use EgldOrEsdtTokenIdentifierType
// final invalid2 = type.createValue('invalid format');

Methods

canAcceptValue(dynamic nativeValue) → bool
Checks if type can accept the given native value.
inherited
createValue(dynamic nativeValue) → TokenIdentifierValue
Creates TokenIdentifierValue from string or bytes.
override
createValueOrThrow<T extends TypedValue>(dynamic nativeValue) → T

Available on AbiType, provided by the AbiTypeOrThrowExtensions extension

Creates a TypedValue from native value and ensures it matches expected type.
equals(AbiType other) → bool
Checks type equality based on fully qualified names.
inherited
hasClassOrSuperclass(String name) → bool
Checks if instance is or extends the specified class.
inherited
hasExactClass(String name) → bool
Checks if instance is exactly the specified class.
inherited
isAssignableFrom(AbiType other) → bool
Checks if type can be assigned from other type.
inherited
isValidValue(dynamic value) → bool

Available on AbiType, provided by the AbiTypeExtensions extension

Checks if the value is valid for this type.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
requireType<T extends AbiType>(String message) → T

Available on AbiType, provided by the AbiTypeValidationExtensions extension

Ensures this type is an instance of T, throwing with a custom message if not.
toMap() → Map<String, dynamic>
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
