smoldot 1.3.1

A Dart wrapper for smoldot-light, providing a lightweight Polkadot/Substrate client implementation via Rust FFI bindings

1.3.1

• Upgraded smoldot-light from 1.2.0 to 1.3.1 (core smoldot 1.2.0 → 2.1.0)
• The C ABI (the FFI entry points and native/smoldot.h) is unchanged across this upgrade, so the Dart bindings are identical and existing code keeps working — this is a native rebuild and behavioural revalidation, not a source change
• Bumped kSmoldotLibVersion to 1.3.1, realigning the package version with the wrapped smoldot-light release. Desktop consumers re-run dart run smoldot:setup to fetch the signed smoldot-v1.3.1 prebuilt; the cache is keyed by version, so the new library installs alongside the old one rather than overwriting it

1.2.1

• Chain now exposes the raw JSON-RPC interface: sendJsonRpc(String), nextJsonRpcResponse() -> Future<String>, and jsonRpcResponses -> Stream<String>. The caller owns request ids and subscription correlation; the JsonRpcHandler export is now RawJsonRpc.

1.2.0

• Realigned the package version to track the wrapped smoldot-light Rust crate version (previously 0.1.x); from now on the package version mirrors the compatible smoldot-light release
• Upgraded smoldot-light from 0.18.0 to 1.2.0 (core smoldot 0.20.0 → 1.2.0)
• Added the required statement_protocol_config field (new in smoldot-light 1.0.0) to the add_chain configuration; defaults to None (statement-store networking disabled), preserving previous behaviour
• Pinned the Rust build toolchain via rust/rust-toolchain.toml (smoldot-light 1.2.0 depends on Rust edition 2024, requiring rustc ≥ 1.85)
• Fixed the ffigen header entry-point to point at the generated native/smoldot.h
• Added optional AddChainConfig.statementStore (StatementStoreConfig) to enable Substrate's statement-store protocol per chain (new in smoldot-light 1.0.0); disabled by default
• Added SubstrateRpcMethods constants for the newer JSON-RPC API now available (chainHead_v1_*, transaction_v1_*, bitswap_v1_get, statement_*)
• Added dart run smoldot:setup (bin/setup.dart) to download a signed prebuilt native library for the current desktop platform from the GitHub Release, verify its Ed25519 signature, and install it into a per-user cache the loader finds automatically — no Rust toolchain required. Currently covers desktop Linux/macOS/Windows on x64+arm64; mobile prebuilts come later
