value property

num Function(T, K, int, Iterable<T>) value
getter/setter pair

The value accessor.

final stack = Stack(…)..value = (d, key, i, data) => d[key];

stack.value; // (d, key, i, data) => d[key]

The value accessor defaults to:

value(d, key, i, data) {
  return d[key];
}

CAUTION: The default value accessor assumes that the input data is an list of maps exposing named properties with numeric values. This is a “wide” rather than “tidy” representation of data and is no longer recommended. See Stack.call for an example using tidy data.

Implementation

num Function(T, K, int, Iterable<T>) value;
