enum Shape { square, circle, triangle }

final message = shape.when(
square: () => 'I am a Square',
circle: () => 'I am a Circle',
triangle: () => 'I am a Triangle',
);
print(message); // I am a Circle

// all cases may not be handled but `orElse` cannot be null
final canBeRotated = shape.maybeWhen(
circle: () => false,
orElse: () => true,
);
print('Can be rotate: $canBeRotated'); // false

// equivalent to print(shape == Shape.circle)
print('The shape is circle: ${shape.isCircle}'); // true
print('The shape is Square: ${shape.isSquare}'); // false
print('The shape is Triangle: ${shape.isTriangle}'); // false
