eth_url_parser 0.2.0

A Dart library for parsing and building Ethereum URLs according to ERC-681. Supports ERC-20 transfers, ENS names, and chain IDs.

0.2.0

Strict EIP-681 compliance. Fixes silent precision loss on the money path.

• Fixed: amounts are now parsed and formatted with BigInt — values above int64 (~9.22 ETH in wei) no longer lose wei silently through num.parse
• Fixed: build no longer corrupts amounts via lossy toStringAsExponential — trailing zeros compress into an exact exponent (2014000000000000000 → 2.014e18), anything else stays plain decimal
• Fixed: addresses are validated as exactly 40 hex digits; non-hex 40-character strings are rejected, and a 0x payload never falls back to ENS (hex takes precedence per the spec)
• Added: bare ENS targets (ethereum:vitalik.eth, ethereum:doge-to-the-moon.eth) parse per the spec grammar
• Added: the scientific-notation number grammar is enforced exactly — the exponent must be ≥ the number of decimals (1.5e0 is rejected)
• Breaking: only the spec-defined pay- prefix is accepted; arbitrary ERC-831 prefixes (foo-) now throw
• Breaking: all malformed input throws FormatException with a descriptive message (previously a mix of bare Exception and raw RangeError on short input)
• Breaking: QueryString.parse uses strict RFC 3986 percent-decoding; + is a literal plus (the number grammar's sign), not a space
• Validated chainId as decimal digits and the transfer address parameter as a valid address or ENS name
• Breaking: EthUrlParser and QueryString can no longer be instantiated — both are static-only utility classes
• 100% dartdoc coverage of the public API, enforced by the public_member_api_docs lint and strict analyzer language checks
