| /// |
| /// The argument entryPoint specifies the entry point of the spawned isolate. |
| /// It must be a top-level function or a static method that takes one argument - |
| /// that is, one-parameter functions that can be compile-time constant function |
| /// values. It is not allowed to pass the value of function expressions or |
| /// an instance method extracted from an object. |
| /// |
| /// The entry-point function is invoked with the initial message. Usually |
| /// the initial message contains a SendPort so that the spawner and spawnee can |
| /// communicate with each other. |
| /// ... |
| /// Returns a future that will complete with an Isolate instance if |
| /// the spawning succeeded. It will complete with an error otherwise. |
