|   Info   |    ✅     |   ✅    |

## Details

**DO** use library prefixes for configured libraries to avoid name conflicts and increase code readability.

```dart title="Bad"
import 'dart:developer';
import 'dart:math';

print(log(e));
log('message');
```

```dart title="Good"
import 'dart:developer' as developer;
import 'dart:math' as math;

print(math.log(math.e));
developer.log('message');
```

## Usage

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

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

## Options

| Option      | Type           | Description                                    | Default Value |
| ----------- | -------------- | ---------------------------------------------- |:-------------:|
| `libraries` | `List<String>` | Libraries that must be imported with a prefix. |     `[]`      |

To configure which libraries require a prefix, add the `libraries` under `plugins > pyramid_lint > options`:

```yaml
plugins:
  pyramid_lint: <version>
    diagnostics:
      prefer_library_prefixes: true
    options:
      prefer_library_prefixes:
        libraries:
          - dart:developer
          - dart:math
          - package:http/http.dart
```
