EventChannel constructor Null safety
- String name,
- [MethodCodec codec = const StandardMethodCodec(),
- BinaryMessenger? binaryMessenger]
Creates an EventChannel with the specified name.
The codec used will be StandardMethodCodec, unless otherwise specified.
Neither name nor codec may be null. The default ServicesBinding.defaultBinaryMessenger
instance is used if binaryMessenger
is null.
Implementation
const EventChannel(this.name, [this.codec = const StandardMethodCodec(), BinaryMessenger? binaryMessenger])
: assert(name != null),
assert(codec != null),
_binaryMessenger = binaryMessenger;
