dartsv 1.1.3

Dart Library for interacting with the Bitcoin network. This library is especially well-suited for use in developing Flutter applications.

1.1.3

BugFix: Uint64 conversion errors with Dart2JS / Flutter Web

• Removed all direct reading and writing of Uint64 types. Dart2JS can't handle the size.

1.1.2

• Fixed bugs that prevented large data pushes from being accepted by network

1.1.1

• downgraded test dependencies to for Flutter compatibility

1.1.0

• Exposed the DUST LIMIT and default feePerKb settings on the Transaction so user can manually change these.
• Also exported the TransactionInput class
• Added a property on the Transaction class that exposes the SigHash Preimage after signing.
• Add missing padding for Wif Format
• Add Javascript target support for Flutter/Web
• added additional test coverage for signatures
• added typing and convenience methods to HD key management
• Removed the inline code example
• Dart Version bump to include the 3.x branch

1.0.2

• Added convenience method on HDPublicKey for getting SVPublicKey
• Strongly typed hexadecimal string returned for xprivkey in HDPrivateKey

1.0.1

Resolved Null-safety warnings on project build

Building an example project threw up some warnings related to the
pointycastle primitives and null-safety. I've made modifications to library
implementation to resolve these compiler warnings.

1.0.0

• Null-Safety Update
• All dependencies have been upgraded or replaced with null-safe equivalents.
• Minimum Dart version is now 2.12.2

0.4.3

• Bugfix: Padded s-values to prevent invalid signatures
• Bugfix: Force 256-bit Private Keys to prevent invalid WIF exports
• Update: Updated example code to import latest major version of lib

0.4.2

• Bugfix: DataBuilder has script construction error for PUSHDATA transactions.

0.4.1

• Bugfix: Bitcoin-Signed-Messages sometimes generate Signatures with short r-values of only 62 bytes length. This causes compact signatures to fail verification. This is now fixed.

0.4.0

• Fixed a script behaviour bug. When using "add()" to update the SVScript's contents the "toHex()" method failed to serialize the additional content.
• Added a method to support generic data-only Locking Script Builders.
• Upgraded the cryptographic library dependency to the new PointyCastle 2.0.1

0.3.3

• Added Electrum-style ECIES (elliptic curve integrated encryption scheme) support

0.3.2

• API Exports
• Bug fix on testnet address encoding length
• DataBuilder modifications
• Added detection to TransactionOutput for P2PKH output
• Downgraded the required SDK version to 2.7.0. Aqueduct chokes on Dart 2.8+

0.3.1

New Feature

• Added DataLockBuilder to allow composing a simple data output script

Bug Fixes

• Bug fix submited by chen610620 for index bug on signing Transaction Inputs. The bug prevented signing of inputs other than the first one.

0.3.0

This represents a rather major refactor of the way in which the Script Builder
interface works. I have completely decoupled the creation of Custom Scripts
from the SDK internals.

NOTE: This release is not backwards-compatible with earlier versions
of the SDK, and contains breaking changes. Please see below.

What's New

• P2PKHUnlockBuilder, P2PKHLockBuilder
• P2MSUnlockBuilder, P2MSLockBuilder
• P2SHUnlockBuilder, P2SHLockBuilder
• P2PKLockBuilder, P2PKUnlockBuilder
• Deep refactor of the way that TransactionInput processes scriptSig
• Bugfix related to script serialization
• New API on SVScript to parse and serialize to ASM format
• Resolved one bitcoind MultiSig test vector which failed to pass (it was the last holdout)

Please note that this update makes small but important changes to how one composes a
Transaction instance in conjunction with an UnlockingScriptBuilder and a LockingScriptBuilder
instance. Review the example code and test cases to familiarize yourself with the new API.
