Any issues relating to the Dart upgrade will be tracked here

I had previously been developing a simple app to record data into the Ethereum blockchain, and had used the web3.js package because I was in a javascript/Angular/browser world. I've now switched over to a flutter/dart native device application and will be trying to use this package. I had made some accounts using 'geth', and then, in my application, enabled them to send transactions with 'eth.personal.unlockAccount(....)', providing the method with a dynamically-decided-on account. I see here that sending a transaction had a comment that the account must be unlocked, suggesting no inbuilt/automatic way of unlocking an account. Does this package provide any mechanism to do that? I see a 'geth --unlock --password ...', but this suggests firing up another geth instance. I also see a 'geth attach', but this suggests that it sets up an interactive javascript environment to the geth node, and I'm not clear if that's usable. So I'm not clear on how to programmatically unlock an account. I guess one might permanently unlock any accounts that might send transactions, but that seems rather insecure. Any thoughts or guidance on how I might approach this? Thanks.

I have a requirement of generating 12 word mnemonics in flutter app. Is there a way in this library to do this. Moreover , I have a node.js code and how can I run it inside webview flutter.

hey there!
I'm eager to implement this and start using this package. I only know Flutter, no idea of React or JavaScript development. Can you give me some guidance about how to implement this and the main functions available to use it?
Use geth goerli and metamask.
Appreciate any help! Telegram: @itsencrypted or [email protected]

Tk you!

Update the package to use Github CI, sbom, linter etc. and add funding links

Mnemonics, private key -> public key -> address, etc

Hi

I want to use port 443 at url.
but, code if (!puri.hasPort) in Ethereum::_validateUri() dose not work.

I had setting port 443, but .hasPort is always false.
How can I use 443 port?

Thank you.

Hi,

I have this to try out on Quorum.

  Future<EthereumBlock> getBlockByNumber(int blockNumber) async {
    final block = EthereumDefaultBlock()..number = blockNumber;
    return await ethClient.eth.getBlockByNumber(block, full: false);
  }

All I have on the response was:

Ethereum Block :
  Number : null
  Hash : null
  Parent Hash : null
  Miner : null
  Difficulty : null
  Gas Used : null
  Time : null
}

Should be the same for ethereum, or quorum as nothing much has changed I guess.
Can you point in the right direction on how to get the block info?

Thanks.

As Ethereum address may start from 0x0..., therefore, use safeParse to convert address to BigInt will lost the leading 0. After that, when convert the BigInt back to address, the beginning 0 will be eat.
This happen during call the "getBalance" function. For example, in /test/ethereum_common.dart, when call client.eth.getBalance, the address is convert from String to BigInt, and inside the getBalance, this same BigInt is convert to String, unfortunately, the leading 0 is cut during conversion.
By the way, "Future getBalance" return an int, which will be wrong when the balance is big enough., so here return BigInt, i.e. "Future getBalance"

Raised for users to add what they would like the package to support, also this will track any re-implementation work if the Ethereum RPC interface is updated.
