This library contains types that allow for executing code in a spawned isolate, perhaps with additional imports.
Subclass Executable
and override its execute
method. Invoke Loner.executeWithType
, passing in that subclass.
The code in execute
will run in another isolate. Any value it returns will be returned by Loner.executeWithType
.
A returned value must be a primitive type (anything that is encodable as JSON). You may pass parameters to the other isolate by providing a message map.
Example:
class Echo extends Executable {
Echo(Map<String, dynamic> message)
: echoMessage = message['echo'],
super(message);
final String echoMessage;
@override
Future<dynamic> execute() async {
return echoMessage;
}
}
Future main() async {
final result = await Loner.executeWithType(Echo, message: {'echo': 'hello'});
assert(result == 'hello');
}
