Issue
Code:
class MyColor {
final Color one;
final Color two;
MyColor({
this.one = Colors.black,
this.two = one.withOpacity(0.5), // error
});
}
Is there any way to assign the value of one
to two
in the constructor itself, I want all fields to be final
.
Solution
class MyColor {
final Color one;
final Color two;
MyColor({
this.one = Colors.black,
Color? two,
}) : two = two ?? one.withOpacity(0.5);
}
