int a = 10;

int b = 5;

a -= b;  // a = a - b -> 10

a *= b;  // a = a * b -> 50

a %= b;  // a = a % b -> 0

int? a;

int b = 5;

int c = a ?? b;  // c = 5, since a is null

a ??= b;          // a = 5, if a was null

print(a?.toString());  // prints "5" if a is not null

int d = a!;         // Throws error if a is null
