Why jsArgs.add doesn't work ?

  JSArray<JSObject>? _convertArgs(List<dynamic>? args) {
    if (args == null) {
      return null;
    }
    final jsArgs = JSArray<JSObject>();
    for (final arg in args) {
      if (arg is String) {
        jsArgs.add(arg.toJS);
      } else if (arg is int) {
        jsArgs.add(arg.toJS);
      } else if (arg is bool) {
        jsArgs.add(arg.toJS);
      }
    }
    return jsArgs;
  }

Issue with estimateGas

Error

main.js:179 Error estimateGas: TypeError: Cannot read properties of null (reading 'toString')
    at formatUnits (index-BR7LYkqh.js:39854:13)
    at formatGwei (index-BR7LYkqh.js:39864:10)
    at new EstimateGasExecutionError (index-BR7LYkqh.js:41059:43)
    at getEstimateGasError (index-BR7LYkqh.js:41089:10)
    at estimateGas$1 (index-BR7LYkqh.js:41129:11)

Because it tries to convert nullable bigint

So i try to fix it with

  JSEstimateGasParameters get toJS => JSEstimateGasParameters(
        accessList: accessList?.jsify() as JSArray<JSObject>?,
        account: account?.toJS,
        chainId: chainId?.toJS,
        data: data?.toJS,
        gas: gas?.toJS ?? BigInt.zero.toJS,
        gasPrice: gasPrice?.toJS ?? BigInt.zero.toJS,
        maxFeePerGas: maxFeePerGas?.toJS ?? BigInt.zero.toJS,
        maxPriorityFeePerGas: maxPriorityFeePerGas?.toJS ?? BigInt.zero.toJS,
        nonce: nonce?.toJS,
        to: to?.toJS,
        type: type?.toJS,
        value: value?.toJS,
      );

But i have a FeeConflictError error because Cannot specify both a gasPrice and a maxFeePerGas/maxPriorityFeePerGas.
Use maxFeePerGas/maxPriorityFeePerGas for EIP-1559 compatible networks, and gasPrice for others.
