This package allows the building of AES70/OCA client applications in Flutter, presenting a bridge between FlutterSwift and SwiftOCA. OCP.1 values are re-encoded using the chosen Flutter codec.
Once Swift Package Manager is merged into Flutter, this package will become a Flutter plugin with a Dart API and some example widgets for common OCA controls. Until then you will need to add an explicit dependency to your Xcode project and implement the widgets according to the channel protocol below.
In the definitions below, <object-id> is one of:
<dotted-class-id>@<class-version>:<hex-ono><hex-ono>
For example, 1.1.3@3:80001000, or 1.1.3:80001000 (will default to class version 3), or 80001000 (will query device over network to determine class, if not already resolved).
- Channel is
oca/method - Method syntax is
<object-id>/<dotted-method-id>(with no leading 0x) - Arguments are
List<Uint8List>where each item is an encoded parameter to be passed to the OCA device - Return value is [UInt8]. The response parameter count is not returned.
This will mostly be useful for testing, unless you wish to build your own OCP.1 serializers in Dart.
- Channel is
oca/event - Listener parameter is
<object-id>/<dotted-property-id> - Event data is the encoded property value
- Channel is
oca/get_property - Listener parameter is
<object-id>/<dotted-property-id> - Arguments are null
- Return value is the encoded property value
- Channel is
oca/set_property - Listener parameter is
<object-id>/<dotted-property-id> - Arguments are the encoded property value
- Return value is null
- Channel is
oca/connection_state - Listener parameter is ignored
- Event data is
Ocp1ConnectionStateinteger raw value
