toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  String all = '{'
      'tradeId=$tradeId, productId=$productId, price=$price, size=$size, '
      'time=$time, side=$side, bid=$bid, ask=$ask'
      '}';
  return all;
}
