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 totalOut = calculateTotalOutput();
return 'MsgTx(txid: ${txid.substring(0, 8)}..., '
'inputs: ${txIn.length}, outputs: ${txOut.length}, '
'value: $totalOut sats, size: $serializedSize bytes)';
}
