A value which is asynchronously initialized on the first access. Nullable implementation of LazyCellAsync
Equality: Cells are equal if they have the same evaluated value or are unevaluated.
Hash: Cells hash to their evaluated value or hash the same if unevaluated.

Methods
-
call(
) → T - Returns the previously evaluated asynchronous value of the function passed into the constructor. Will panic if the value has not yet been evaluated. Prefer force for safer context.
-
force(
) → Future< T> - Lazily evaluates the function passed into the constructor.
-
isEvaluated(
) → bool - Returns true if this has already been called, otherwise false.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
