# kotlin_flavor

Are you Android-app engineer, and eager to use scope functions also in Dart?

Yes, `kotlin_flavor/scope_functions` provides it for you! :)

```dart

import 'package:kotlin_flavor/scope_functions.dart'

bool handle(Shop selectedShop) {

  return selectedShop?.let((shop) {

    navigateTo(shop.location);

    return true;

  }) ?? run(() {

    navigateToDefaultPosition();

    return false;

  });

}

```

## kotlin_flavor/scope_functions

### let

Often used for executing a code block only with non-null values.

```

someNullable?.let((it) { ... });

```

### also

Used for additional actions that don't alter the object, such as logging or printing debug information.

```

something.also((it) { ... }); // returns something.

```

### run

Used for evaluating a block of several statements where an expression is required.

```

someNullable ?? run(() {

  var defaultValue = ......;

  // several process...

  return defaultValue;

});

```

## Development

```

$ docker-compose pull

$ docker-compose run --rm dart

```

will build a Dart development environment for you.

Ensure all test successfully pass, every after you change some codes:

```

$ pub run test

```
