update abstract method

Future<void> update(Map<String, dynamic> value)

Write the enumerated children at this Firebase location when the client is disconnected (due to closing the browser, navigating to a new page, or network issues). This will overwrite only children enumerated in the 'value' parameter and will leave others untouched.

If the values specified for the children are objects, update will merely set those values. It will not recursively 'update' those children. Passing null as a value for a child is equivalent to calling remove() on that child.

Implementation

Future<void> update(Map<String, dynamic> value);
