polkadart 1.0.0

polkadart: ^1.0.0 copied to clipboard

Breaking Changes #

• Extrinsic API completely redesigned - Manual SigningPayload and ExtrinsicPayload replaced with fluent ExtrinsicBuilder
• Removed SigningPayload, ExtrinsicPayload, and related classes
• Removed Transfers class with static methods - replaced by Balances module
• Removed substrate.dart and scale_codec.dart wrapper libraries
• Removed provider.dart as standalone export - now part of apis library
• Multisig API changed from static methods to instance-based pattern

Added #

• ExtrinsicBuilder - New fluent API for building extrinsics:
  • Factory constructor: ExtrinsicBuilder.fromChainData() for automatic chain data integration
  • Configuration methods: .nonce(), .tip(), .era(), .immortal(), .assetId(), .metadataHash()
  • Signing methods: signAndBuild(), signBuildAndSubmit(), signBuildAndSubmitWatch()
  • Static quickSend() method for one-liner transaction submission
  • SigningCallback typedef: Uint8List Function(Uint8List payload)
• Balances module with builder pattern:
  • Balances.transfer, Balances.transferKeepAlive, Balances.transferAll, Balances.forceTransfer, Balances.forceSetBalance, Balances.setBalanceDeprecated
  • Three address input methods: .to() (SS58), .toAccountId() (pubkey), .toMultiAddress() (advanced)
  • Automatic conversion to RuntimeCall via .toRuntimeCall(chainInfo)
• ChainDataFetcher - Parallel fetching of chain state with structured ChainData return
• CallIndicesLookup - Helper for resolving pallet and call indices from metadata
• MultisigAccount class - Automatic multisig address derivation with validation
• Enhanced MultisigStorage:
  • Static fetch() method for async retrieval
  • Status methods: hasApproved(), isDepositor(), isFinalApproval(), isComplete()
  • getStatus() method returning MultisigStorageStatus object

Changed #

• Multisig refactored from static methods to instance-based:
  • Constructor: Multisig({required provider, required chainInfo, required multisigAccount})
  • Uses SigningCallback instead of KeyPair for signing
  • Instance methods: createAndFundMultisig(), createCallData(), initiateTransfer(), approveAsMulti(), asMulti(), cancel()
• Direct exports of polkadart_scale_codec and substrate_metadata in main library
• Provider classes moved to /lib/apis/provider.dart as part of APIs library

Removed #

• primitives/runtime_metadata.dart - replaced by direct substrate_metadata usage
• primitives/transfers.dart - replaced by balances module
• Multisig helper files: multisig_meta.dart, signatories.dart, signatory.dart, exceptions.dart, extensions.dart, utilities.dart
• Extrinsic files: abstract_payload.dart, signing_payload.dart, extrinsic_payload.dart, signature_type.dart
• Signed extensions: asset_hub.dart, signed_extensions_abstract.dart, substrate.dart
