I am having a flutter app, and want to connect it with ganache for ether transfer. But when I connect it with my real device it has given me the following error.
[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: SocketException: Connection refused (OS Error: Connection refused, errno = 111), address = 127.0.0.1, port = 52035
String rpcUrl = "http://127.0.0.1:7545";
String wsUrl = "ws://127.0.0.1:7545/";
sendEther() async {
Web3Client client = Web3Client(rpcUrl, Client(), socketConnector: () {
return IOWebSocketChannel.connect(wsUrl).cast<String>();
});
String privateKey =
"cce548f8263f25d63613bb48b87391b9c83f07a3ede4a5f8380549f93c2ca05f";
Credentials credentials =
await client.credentialsFromPrivateKey(privateKey);
EthereumAddress ownAddress = await credentials.extractAddress();
EthereumAddress reciever =
EthereumAddress.fromHex("0x3B0ae8eecdFe232b453Ea107B65B2B7FFE8d46B9");
print("#################");
print(ownAddress);
client.sendTransaction(
credentials,
Transaction(
from: ownAddress,
to: reciever,
value: EtherAmount.fromUnitAndValue(EtherUnit.ether, 1)
));
}
This is my code to send ether to another account.
Ganache localhost RPC SERVER "HTTP://127.0.0.1:7545". How to work it on real device?
I have the following problem: I have a .NET API running on my local machine at https://localhost:5001. When I execute a request in Postman, it works totally fine, but when executing the same API call in Dart, it won't work.
In Postman https://localhost:5001 will respond with a 401 or a 200 Statuscode.
When I execute the exact same URL in Flutter, it will give me a timeout:
Flutter Devtools
When using https://localhost:5001 in Flutter -> SocketException: OS Error: Connection refused, errno = 111, address = localhost, port = 41838
When using https://192.168.0.154:5001 in Flutter -> SocketException: OS Error: Connection timed out, errno = 110, address = 192.168.0.154, port = 44624
Im executing the following code:
var response = await http.get(url);
if(response.statusCode == 200) {
print(response.body);
}else{
throw Exception('Failed to fetch');
}```
In flutter when i try to upload mp4 video to my local server return me this
SocketException: OS Error: Connection reset by peer, errno = 54, address = 192.168.178.117, port = 52699
i used
AssetEntity asset = toUpload[i];
final byteData = await asset.originBytes;
var request = http.MultipartRequest('POST', url)
..fields['fileName'] = _imageNames[i]
..files.add(http.MultipartFile.fromBytes('image', byteData));
Is this a client problem or a server problem ?
I use this version of http
http: ^0.12.2
The issue was in my backend.
Using quarkus in application.properties i add

I have these exceptions on different phones, some correct way to handle them.

I have an application that has a timeout to upload images to the service and I think that is generating these exceptions, although I do have a try block, but the exceptions are still generated in production. Thanks for any help
