Warns when a return statement inside an if block is equal to the return statement after it.

Example​

❌ Bad:

final value = 1;

int function() {
  if (value == 2) { // LINT: Return statement inside this 'if' block is equal to the return statement after this 'if' block. Try removing this block or checking the return statement for a potential mistake.
    return 1;
  }

  return 1;
}

✅ Good:

final value = 1;

int function() {
  if (value == 2) {
    return 2; // Correct, different return value
  }

  return 1;
}
