RfwFormats

RfwFormats is an Elixir implementation of Flutter's Remote Flutter Widgets (RFW) template parser and binary converter.

Features

• Parse RFW text format library templates and data files
• Encode and decode RFW binary format data and library blobs
• Full compatibility with Flutter's RFW specification

Installation

Add rfw_formats to your list of dependencies in mix.exs:

def deps do
  [
    {:rfw_formats, "~> 0.1.0"}
  ]
end

Usage

The most common use-case is parsing a widget template from text format and converting it to binary format for use with Flutter:

alias RfwFormats.{Text, Binary}

# Parse a widget template from text format
template = Text.parse_library_file("""
import core.widgets;

widget myButton = ElevatedButton(
  onPressed: callback,
  child: Text("Click me")
);
""")

# Convert the template to binary format for Flutter
binary_blob = Binary.encode_library_blob(template)
