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 = '{'
'entryId=$entryId, tradeId=$tradeId, orderId=$orderId, '
'tradeTime=$tradeTime, tradeType=$tradeType, price=$price, size=$size, '
'commission=$commission, productId=$productId, '
'sequenceTimestamp=$sequenceTimestamp, '
'liquidityIndicator=$liquidityIndicator, sizeInQuote=$sizeInQuote, '
'userId=$userId, side=$side'
'}';
return all;
}
