getFeeData method
Returns the current recommended FeeData to use in a transaction.
For an EIP-1559 transaction, the FeeData.maxFeePerGas and FeeData.maxPriorityFeePerGas should be used.
For legacy transactions and networks which do not support EIP-1559, the FeeData.gasPrice should be used.
Implementation
Future<FeeData> getFeeData() async =>
FeeData._(await call<_FeeDataImpl>('getFeeData'));
