### Before

When `RawChip.shape` is provided with a `BorderSide`.

```dart
      body: Center(
        child: RawChip(
          shape: RoundedRectangleBorder(
            side: BorderSide(color: Colors.amber),
            borderRadius: BorderRadius.all(Radius.circular(12)),
          ),
          label: Text('Chip'),
        ),
      ),
```

When `RawChip.shape` is provided with a `BorderSide` and also `RawChip.side` is provided. The  `RawChip.side` overrides the shape's side.

```dart
      body: Center(
        child: RawChip(
          shape: RoundedRectangleBorder(
            side: BorderSide(color: Colors.amber),
            borderRadius: BorderRadius.all(Radius.circular(12)),
          ),
          side: BorderSide(color: Colors.red),
          label: Text('Chip'),
        ),
      ),
```
