how to convert double to int in dart?

I have a code like this

double total = 20.2;
int min = total as int;

flutter build was ok but it was exception on runtime.

I have tried int.parse() but it requires string not double.

Do you have any suggestion?

>Solution :

If you want to round the value :

double total = 20.2;
int min = total.round();

If you want to just truncate the value :

double total = 20.2;
int min = total.toInt();
