Quick Fix: Add Curly Braces Everywhere, does not do for chained if/else

```dart
void foo(bool x, bool y) {
  if (x)
    print(0);
  else if (y)
    print(1);
  else
    print(2);
}
```

Apply at `print(0)`, only `if (x)` is fixed.
```dart
void foo(bool x, bool y) {
  if (x) {
    print(0);
  } else if (y)
    print(1);
  else
    print(2);
}
```

Cannot be applied at `print(1)` initially or after the first fix.
