Hey I'm working on a Eosio blockchain dapp, so for front end I'm using flutter. We have a package Eosdart for connecting flutter to eos blockchain.
Everything was good till here, but the problem comes after this. Actually I'm making a small loan app so it takes lots of float datatype to store at blockchain like interest rate Emi etc. So blockchain part is working properly, problem coming in flutter.
Whenever I'm calling any action on blockchain with flutter app and if that action contains any float value, flutter throws an unhandled exception, saying unknown type : flaot32 Or float64,
After that i looked in the error I find out in eosdart package of flutter for connection blockchain, they have commented the code for float64 and float32 and that's why flutter throwing exception unknown type, coz it's not getting that float32 or float64 datatype
This is what I think about this error.
Please suggest if anyone have any idea,
Also if I'm correct as I said then developers should know about this error and improve this, coz float datatype is necessity without it can't build the app
Also,i tried removing float datatype and putting int and then when i run the same code it runs perfectly
THIS IS MY CODE FOR CALLING ACTION
void requestLoan() {
List<eos.Authorization> auth = [
eos.Authorization()
..actor = 'guru11111111'
..permission = 'active'
];
Map data = {
'borrower': 'borrower3',
'uwr_name': widget.lenderDetailList[widget.index]['acc_name'],
'loan_amnt': loanAmountController.text,
'interest_rate': widget.lenderDetailList[widget.index]['interest_rate'],
'loan_duration': tenureController.text,
};
List<eos.Action> actions = [
eos.Action()
..account = 'microfinance'
..name = 'reqloan'
..authorization = auth
..data = data
];
eos.Transaction transaction = eos.Transaction()..actions = actions;
_eosClient.pushTransaction(transaction, broadcast: true).then((trx) {
print(trx);
});
}
This is my console eRROR

I know this question is not totally on EOS,flutter also comes in here,but as a whole EOS comes in,so please sugguest anything u.
