# Download the prebuilt flutter-tvos engine tarball from GitHub Releases,
|
|
# extract it into a shared cache, and write tvos/Flutter/Generated.xcconfig
|
|
# so Xcode picks it up via FLUTTER_LOCAL_ENGINE.
|
|
#
|
|
# Reads the engine version and reviewed SHA-256 from tvos/engine.version and
|
|
# tvos/engine.sha256. Re-runs are cheap —
|
|
#
|
|
# Usage:
|
|
# tvos/scripts/fetch_engine.sh
|
|
#
|
|
# Env overrides:
|
|
# FLUTTER_TVOS_ENGINE_CACHE — root dir for cached engines (default: ~/.cache/flutter-tvos-engine)
|
|
# FLUTTER_TVOS_RELEASES_URL — base URL for release tarballs (default: github.com/edde746/flutter-tvos)
