What would you like to do?
My First Dart code
class Bicycle {
int cadence;
int _speed = 0;
//we have made speed as read only so we will just use get below to read its value.
//we will update its value using _speed variable.(work as setter)
// and to print the speed value (use _speed which always gets the latest speed value)
int get speed => _speed;
int gear;
Bicycle(this.cadence, this.gear);
void applyBrake(int decrement) {
_speed -= decrement;
void speedUp(int increment) {
_speed += increment;
String toString() => 'Bicycle: $_speed mph';
void main() {
var bike = Bicycle(2, 1);
