Fields

pubspec_name: Option<String>

Dart pub.dev package name (e.g. "my_package"). Used as the name in pubspec.yaml. Defaults to a snake_case derivation of the crate name.

lib_name: Option<String>

Dart library name (the library declaration). Defaults to the pubspec name.

package_name: Option<String>

Dart package name override (e.g. for pub.dev scoped packages).

style: DartStyle

Bridging style. "frb" (default) uses flutter_rust_bridge; "ffi" emits raw dart:ffi source over the cbindgen C library.

frb_version: Option<String>

flutter_rust_bridge version to pin in generated pubspec.yaml. Defaults to template_versions::cargo::FLUTTER_RUST_BRIDGE when unset.

features: Option<Vec<String>>

Cargo features to enable on the binding crate.

extra_dependencies: HashMap<String, Value>

Additional Cargo dependencies for the generated Dart Rust bridge crate.

serde_rename_all: Option<String>

Override the serde rename_all strategy for JSON field names (e.g. “camelCase”, “snake_case”).

rename_fields: HashMap<String, String>

Per-field name remapping. Key is TypeName.field_name, value is the desired binding field name. Applied after automatic keyword escaping.

exclude_functions: Vec<String>

Functions to exclude from Dart binding generation.

exclude_types: Vec<String>

Types to exclude from Dart binding generation.

run_wrapper: Option<String>

Prefix wrapper for default tool invocations.

extra_lint_paths: Vec<String>

Extra paths to append to default lint commands.

core_crate_override: Option<String>

Override the core Cargo dependency name and path for the Dart binding crate. When set, the binding Cargo.toml depends on this crate (resolved as ../../../crates/<override>) instead of the umbrella [crate.name]. Defaults to unset.

exclude_extra_dependencies: Vec<String>

Keys to subtract from the merged extra_dependencies set for this language only.

stub_methods: Vec<String>

Method names whose Rust bridge body should be emitted as unimplemented!().

Use this when a function’s FFI signature (e.g. nested tuples containing Vec<u8>) cannot be represented across the FRB bridge at all. Consumers must list the method names explicitly — this field has no built-in defaults so the knob is library-agnostic.

Example (alef.toml):

[crates.dart]
stub_methods = ["batch_extract_bytes", "batch_extract_bytes_sync"]

target_dep_overrides: Vec<DartTargetDepOverride>

Per-target Cargo dependency overrides for the binding crate.

When set, the emitted Cargo.toml wraps the base core dependency in a [target.'cfg(not(<cfg>))'.dependencies] section and adds a matching [target.'cfg(<cfg>)'.dependencies] block using override_features (and default_features = false when override_default_features = false). Required when the binding has to swap the feature set on a specific target triple, e.g. Android x86_64 dropping ORT-dependent features.

Example (alef.toml):

[[crates.dart.target_dep_overrides]]
cfg = "all(target_os = \"android\", target_arch = \"x86_64\")"
features = ["android-target"]
default_features = false
