toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  return 'UsbDeviceInfo( '
      'bus: $busNumber, '
      'address: $deviceAddress, '
      'vendorId: 0x${vendorId.toRadixString(16).padLeft(4, '0')}, '
      'productId: 0x${productId.toRadixString(16).padLeft(4, '0')}, '
      'class: 0x${deviceClass.toRadixString(16).padLeft(2, '0')}, '
      'subclass: 0x${deviceSubClass.toRadixString(16).padLeft(2, '0')}, '
      'protocol: 0x${deviceProtocol.toRadixString(16).padLeft(2, '0')}, '
      'manufacturer: $manufacturer, '
      'product: $product, '
      'serialNumber: $serialNumber)';
}
