Payjoin Dart Bindings #

Welcome to the Dart language bindings for the Payjoin Dev Kit!

Usage #

dart pub add payjoin

import 'package:payjoin/payjoin.dart' as payjoin;

For OHTTP relay helpers:

import 'package:payjoin/http.dart' as payjoin_http;

The package compiles its Rust library on your machine through a Dart build hook, with the toolchain named in native/rust-toolchain.toml.

Hosted releases are locked. A version from pub.dev ships the native/Cargo.lock it was released with, and the hook builds it with --locked. Every release compiles the same dependency versions, whenever and wherever you build it.
Git dependencies are development builds. A git: dependency on this repository checks out the monorepo layout, which the hook treats as a development build: it builds payjoin-ffi from the checkout, enables test-only helpers and resolves dependencies afresh, without a lockfile. Use a hosted release in production.
Cargo config rustflags do not apply. The hook sets CARGO_ENCODED_RUSTFLAGS to strip build paths from the library, and Cargo then ignores build.rustflags and target.*.rustflags from any Cargo config file for this build.
