# toString method

1. @override

String toString()
override

Returns the ISO 8601 string representation with timezone information.

The format is: `yyyy-MM-ddTHH:mm:ss±HH:mm[ZoneId]`

Example:

    final zoned = ZonedDateTime.of(
      LocalDateTime.of(2023, 12, 25, 15, 30, 45),
      ZoneId.of('America/New_York')
    );

    print(zoned.toString());
    // Output: 2023-12-25T15:30:45-05:00[America/New_York]

## Implementation

    @override
    String toString() {
      final offsetStr = _formatOffset(_offset);
      return '$_localDateTime$offsetStr[${_zone.id}]';
    }
