Is there a Goto function in Dart?
Yes, Dart supports labels. With continue and break you can jump to labels. Below is a quick example of it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | void main() { outerloop: // This is the label name for (var i = 0; i < 5; i++) { print("Innerloop: ${i}"); innerloop: for (var j = 0; j < 5; j++) { if (j > 3 ) break ; // Quit the innermost loop if (i == 2) break innerloop; // Do the same thing if (i == 4) break outerloop; // Quit the outer loop print("Innerloop: ${j}"); } } } void main() { outerloop: // This is the label name for (var i = 0; i < 3; i++) { print("Outerloop:${i}"); for (var j = 0; j < 5; j++) { if (j == 3){ continue outerloop; } print("Innerloop:${j}"); } } } |
