flutter_freetype #

Cross-platform FreeType bindings for Flutter using FFI on native platforms and WebAssembly on the web.

Features #

• Bindings generated automatically with ffigen
• Native FreeType is built automatically by the Flutter plugin_ffi build (Android/iOS/macOS/Linux/Windows)
• Web/Wasm uses the bundled wasm/dist/freetype.{js,wasm}

Installation #

dependencies:
  flutter_freetype: ^1.0.0

Binding generation #

dart run ffigen

Native builds (Android/iOS/macOS/Linux/Windows) #

No manual steps required. The consuming Flutter app builds and bundles the native library automatically (Flutter plugin_ffi).

Usage #

Prefer the async constructor so the same code works on Web/Wasm and native:

import 'package:flutter_freetype/flutter_freetype.dart';

final ft = await Freetype.create();

On Web/Wasm, load fonts from bytes (paths are not supported):

final face = ft.newFaceFromBytes(fontBytes);

If you need the raw ffigen bindings on native platforms, import:

import 'package:flutter_freetype/flutter_freetype_ffi.dart';

Tests #

• VM (default): flutter test test/vm
• Web/Wasm (optional): RUN_WEB_TESTS=1 ./scripts/test_all.sh
• All (VM only): ./scripts/test_all.sh
