toString method
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=$tradeId, createdAt=$createdAt, '
'productId=$productId, orderId=$orderId, userId=$userId, '
'profileId=$profileId, liquidity=$liquidity, price=$price, size=$size, '
'fee=$fee, side=$side, settled=$settled, usdVolume=$usdVolume'
'}';
return all;
}
