Usage

Usage of this package is dead simple as it is simply a neatly wrapped set of two maps with some convenience extensions.

16-Bit Hexadecimal

Using hex strings.

final int key = int.parse('0x00E0', radix: 16); // Parse 16-bit hex in Dart using integer with radix 16

final UUIDAllocation uuidServiceId = BluetoothIdentifiers.uuidServiceIdentifiers[key];

print(uuidServiceId); // null


final String companyIdentifier = BluetoothIdentifiers.companyIdentifiers[key];

print(companyIdentifier); // 'Google'

copied to clipboard

Using convenience map extension function.

final UUIDAllocation uuidServiceID = BluetoothIdentifiers.uuidServiceIdentifiers
  .elementForHex('0xFCF1');

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


final String companyIdentifier = BluetoothIdentifiers.companyIdentifiers
  .elementForHex('0x00E0'); 

print(companyIdentifier); // 'Google'

copied to clipboard

What if I also need calculated key?

final MapEntry<int, UUIDAllocation> uuidServiceIDEntry = BluetoothIdentifiers.uuidServiceIdentifiers
  .entryForHex('0x00E0');

print(uuidServiceIDEntry.key); // 224
print(uuidServiceIDEntry.value); // null


final MapEntry<int, String> companyIdentifierEntry = BluetoothIdentifiers.companyIdentifiers
  .entryForHex('0x00E0');

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

Unsigned Decimal

Unsigned decimals may also be used either in Dart hex notation or raw integer form for programmatic ease-of-use.

final UUIDAllocation uuidServiceId = BluetoothIdentifiers.uuidServiceIdentifiers[0x00E0];

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


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

print(companyIdentifier); // 'Google'

copied to clipboard

which is exactly equivalent to

final UUIDAllocation uuidServiceId = BluetoothIdentifiers.uuidServiceIdentifiers[224];

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

final String companyIdentifier = BluetoothIdentifiers.companyIdentifiers[224];

print(companyIdentifier); // 'Google'
