Usage

Usage of this package is dead simple as it is a neatly wrapped set of maps with int key type.

Direct Fetching

Direct fetching may be done either via raw integer, or hex literal.

final UUIDAllocation uuidServiceId = BluetoothIdentifiers.uuidServiceIdentifiers[64753];

print(uuidServiceID); // UUIDAllocation(type: '16-bit UUID for Members', registrant: 'Google LLC')


final String companyIdentifier = BluetoothIdentifiers.companyIdentifiers[0x00E0];

print(companyIdentifier); // 'Google'

Key Calculation

Regular calculation of keys

Calculating key from hex string example

final int key = int.parse('0x00E0', radix: 16);

Calculating key from byte list example

final int start = 0;
final Uint8List bytes = Uint8List.fromList([0, 224]);

final int key = bytes.buffer.asByteData().getUint16(start);

Instead of grinding away at calculating your own keys for the maps in order to follow general usage, the package exposes simple Map extension functions which may be used to reduce a lot of tedious boiler-plate.

Convenience extensions

final UUIDAllocation uuidServiceId = BluetoothIdentifiers.uuidServiceIdentifiers.elementForHex('0x00E0');

print(uuidServiceID); // UUIDAllocation(type: '16-bit UUID for Members', registrant: 'Google LLC')


final Uint8List bytes = Uint8List.fromList([0, 224]);
final String companyIdentifier = BluetoothIdentifiers.companyIdentifiers.elementForByteArray(bytes);

print(companyIdentifier); // 'Google'

What if I also need calculated key?

final MapEntry<int, UUIDAllocation> uuidServiceIDEntry = BluetoothIdentifiers.uuidServiceIdentifiers
  .entryForHex('0xFCF1');

print(uuidServiceIDEntry.key); // 64753
print(uuidServiceIDEntry.value); // UUIDAllocation(type: '16-bit UUID for Members', registrant: 'Google LLC')

final Uint8List bytes = Uint8List.fromList([0, 224]);
final MapEntry<int, String> companyIdentifierEntry = BluetoothIdentifiers.companyIdentifiers
  .entryForByteArray(bytes);

print(companyIdentifierEntry.key); // 224
print(companyIdentifierEntry.value); // 'Google'
