Devopsdao is a community driven project to build an ecosystem of blockchain software development, as a part of our community contribution effort we have took the development of webthree library (a fork of web3dart) in order to keep Dart language ecosystem consistent with the recent updates of Ethereum network.

WebThree

WebThree — a web3 library for dart that allows you to interact with a local or remote ethereum node using HTTP or WebSocket. Suports custom credentials providers like WalletConnect and Metamask.

Fork of original web3dart 2.3.5 by simolus3, incorporating all changes from other forks.

Features

Connect to an Ethereum node with the rpc-api, call common methods Send signed Ethereum transactions Generate private keys, setup new Ethereum addresses Call functions on smart contracts and listen for contract events Code generation based on smart contract ABI for easier interaction

2.5.0 first WebThree version

Renaming library to WebThree in order to maintain a community developed fork. Bumping version number to 2.5.0, pull requests are greatly appreciated. No breaking changes were made.

the reason for creating this fork from https://github.com/simulous/web3dart 2.3.5 was that web3dart 2.4.1 currently published at https://pub.dev/packages/web3dart/ Github repo https://github.com/xclud/web3dart has factored out contract generator and metamask integration, making a breaking change. The following changes were implemented:

  1. added stubs for dart_wrappers.dart and dart:js, added conditional dependencies import to metamask example in order to support web and other platform builds from a single codebase.

  2. fix signPersonalMessage to use modern personal_sign instead of eth_sign

  3. fix type issues in getTransactionHistory

  4. Merged all reasonamble commits from the forks network, thank you @@simolus3 @superkeka @alexeyinkin @xclud @TheGreatAxios @rgplvr @thegamenicorus @MahmoudKhalid @superkeka from @superkeka/web3dart

  5. Make EthereumAddress Comparable

  6. StateMutability error when parsing json abi that contains an event simolus3/web3dart#13

  7. Make getTransactionByHash nullable

  8. Expose number utility functions simolus3/web3dart#3

  9. decodeCall Uses the known types of the function parameters to parse them from the binary call data. The reverse of [encodeCall].

  10. make rpc call public

  11. Add block number to BlockInformation, add BlockInformationWithTransactions, add getBlockByNumberWithTransactions.

  12. API Documentation on how to create the wallet files, HD wallets simolus3/web3dart#2

  13. Fix fetching mempool transactions that do not yet have blockHash

  14. Erc20 class support for name, symbol and decimals functions. from @GangemiLorenzo/web3dart

  15. add sender to generated contract read

  16. add argSender to generated contracts from @kryptogo/web3dart

  17. add toMap for tx receipt

  18. add value for eth_call from @thegamenicorus/web3dart

  19. fix filter not found

  20. add getTransactionHistory

  21. keep rpc running

  22. add getPendingTransactions from @thelazyindian/web3dart

  23. Accept Null message Fix EIP1559Information from @MahmoudKhalid/web3dart

  24. Fix EIP1559Information

  25. Added getGasInEIP1559 method

  26. Added feeHistory method from @rgplvr/web3dart fix fetchChainIdFromNetworkId from @naiba/web3dart

  27. fix uint8list overflow
