Functions Expression => FatArrow:
void main(){
var x = getNumber(10, 20);
print(x * 2);
}
getNumber(int a, int b) => (a * b) + 10;
Opetional Parameter:
void main() {
getNumber(10);
}
[] Bracket is used for optional parameter
getNumber(int x, [int y = 56]) {
print(x * y);
}
Named Parameter:
void main() {
getNumber(10, z: 20, y: 30);
}
getNumber(int x, {int y, int z}) {
print(x);
print(y);
print(z);
var num = (x + y) * z;
print(num);
}
