| * @assertion Future then(dynamic onValue(T value), {Function onError}) |
| * Register callbacks to be called when this future completes. |
| * When this future completes with a value, the onValue callback will be |
| * called with that value. If this future is already completed, the callback |
| * will not be called immediately, but will be scheduled in a later microtask. |
| * . . . |
| * Returns a new Future which is completed with the result of the call to |
| * onValue (if this future completes with a value) or to onError (if this |
| * future completes with an error). |
| * @description Checks that different onValue functions don't conflict with |
| * each other. |
