avoid_empty_else

Empty statements are not allowed in an 'else' clause.

The analyzer produces this diagnostic when the statement after an else is an empty statement (a semicolon).

For more information, see the documentation for avoid_empty_else.

The following code produces this diagnostic because the statement following the else is an empty statement:

void f(int x, int y) {
  if (x > y) {
    print('1');
  } else
    ;
  print('2');
}

If the statement after the empty statement is intended to be executed only when the condition is false, then remove the empty statement:

void f(int x, int y) {
  if (x > y) {
    print('1');
  } else {
    print('2');
  }
}

If there is no code that is intended to be executed only when the condition is false, then remove the whole else clause:

void f(int x, int y) {
  if (x > y) print('1');
  print('2');
}
