# get method

String? get([

1. bool showSuggestions = false

])

Returns the value of the environment variable as a String.

- If the variable is found, its string representation is returned.
- If missing, the defaultValue is used if provided.
- If both are unavailable, returns `null`.

If `showSuggestions` is `true`, it will print a suggestion message with similar keys if available.

### Example

    final dbUrl = Env<String>('DATABASE_URL').get();
    print('Database URL: $dbUrl');

## Implementation

    String? get([bool showSuggestions = false]) {
      String? value = environment.getProperty(_key, defaultValue.toString());

      if (value.isNotNull) {
        return value!;
      }

      if (defaultValue.isNotNull) {
        return defaultValue.toString();
      }

      if (showSuggestions) {
        System.out.println(_messageSuggestion);
      }

      return null;
    }
