## Details

**DO** use `iterable.first` instead of `iterable[0]` or `iterable.elementAt(0)`.

```dart title="Bad"
const numbers = [1, 2, 3];

final firstNumber = numbers[0];
// or
final firstNumber = numbers.elementAt(0);
```

```dart title="Good"
const numbers = [1, 2, 3];
final firstNumber = numbers.first;
```

## Usage

To enable the `prefer_iterable_first` rule, add `prefer_iterable_first` under `plugins > pyramid_lint > diagnostics` in your `analysis_options.yaml` file:

```yaml
plugins:
  pyramid_lint: <version>
    diagnostics:
      prefer_iterable_first: true
```
