FieldDeclaration class abstract
Represents a field (variable) declared within a Dart class, extension, enum, or mixin.
Provides access to its type, modifiers (final
, late
, const
, static
),
and the ability to read or write its value at runtime.
Example
class Person {
final String name;
static int count = 0;
}
final field = reflector.reflectField(Person, 'name');
print(field.getIsFinal()); // true
print(field.getTypeDeclaration().getName()); // String
final p = Person('Jet');
print(field.getValue(p)); // Jet
