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() {
final ret = 'Ethereum Transaction Receipt:'
'\n'
' Transaction Hash : $transactionHash'
'\n'
' Block Number: $blockNumber'
'\n'
' Block Hash : $blockHash'
'\n'
' Transaction Index : $transactionIndex'
'\n'
' Contract Address : $contractAddress'
'\n'
' Gas used : $gasUsed'
'\n';
return ret;
}
