initializeGhosttyVteWeb function

Future<void> initializeGhosttyVteWeb({
  1. String assetPath = 'packages/ghostty_vte_flutter/assets/ghostty-vt.wasm',
})

Package-level setup and lightweight terminal widgets for Flutter.

The wasm runtime can be initialized via initializeGhosttyVteWeb on web before constructing web terminal views. Initializes the Ghostty wasm module on web from bundled Flutter assets.

Call this early in your main() before constructing any terminal views on web targets. This is a no-op on native platforms.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await initializeGhosttyVteWeb();
  runApp(const MyApp());
}
