tokenSupply method Null safety
Returns the supply of Tokens
tokenname
- Name of the Token
contractaddress
- Address from token contract
Example
var supply = eth.tokenSupply(
tokenname: null,
contractAddress: '0x57d90b64a1a57749b0f932f1a3395792e12e7055'
);
Result returned in Wei, to get value in Ether divide resultAbove/1000000000000000000)
Implementation
Future<EtherScanSupplyModel> tokenSupply({
String? tokenName,
String? contractAddress,
}) async {
const module = 'stats';
const action = 'tokensupply';
Map<String, dynamic>? query = {
'module': module,
'action': action,
'apiKey': apiKey,
};
if (tokenName != null) {
query.putIfAbsent('tokenname', () => tokenName);
}
if (contractAddress != null) {
query.putIfAbsent('contractaddress', () => contractAddress);
}
return (await get(query)).fold(
(l) => EtherScanSupplyModel.empty(),
(r) => EtherScanSupplyModel.fromJson(r),
);
}
