We have already seen try , on and catch block now we finally see about the Finally Clause on dart Exception handing.
Finally Clouse means that this block will run compulsory even if we receive any exception or not it's does not matter. This block will run anyhow.
Syntax
Syntax:
try {
.....
}
on Exception1 {
....
}
catch Exception2 {
....
}
finally {
// code that should always execute; whether exception or not.
}
void main()
{
try{
int x= 5 ~/ 0;
print("The x valuse is $x");
}
catch(e , s)
{
print("Excepation : $e");
print(s);
}
finally{
print("Finally Clause");
}
}
Here, we can see that all the block executed even we receive the error of IntegerDivisionByZeroException still final block executed and we can see the output of the this.
