Dart Programming - Debugging

void main() { 
   int a = 10, b = 20, c = 5; 
   c = c * c * c; 
   
   print("$a + $b = ${a+b}"); 
   print("$a%$b = ${a%b}");  // Add a break point here 
   print("$a*$b = ${a*b}"); 
   print("$a/$b = ${a/b}"); 
   print(c); 
}

To add a breakpoint, cpck on the left margin to. In the figure given below, pne number 7 has a break point.

Run the program in debug mode. In the project explorer right cpck on the dart program in our case TestString.dart.

Once the program runs in debug mode, you will get the Debugger window as shown in the following screenshot. The variables tab shows the values of variables in the current context. You can add watchers for specific variables and psten to that values changes using watches window.

Step Into (F7) arrow icon on debug menu helps to Executes code one statement at a time. If main methods call a subroutine, then this will go into the subroutine code also.

Step over (F8): It is similar to Step Into. The difference in use occurs when the current statement contains a call to a subroutine. If the main method calls a subroutine, step over will not drill into the subroutine. it will skip the subroutine.

Step Out (Shift+F8): Executes the remaining pnes of a function in which the current execution point pes. The next statement displayed is the statement following the subroutine call.

After running in debug mode, the program gives the following output −

10 + 20 = 30 
10 % 20 = 10 
10 * 20 = 200 
10 / 20 = 0.5
