gclient now needs to be run with vpython3. Using the wrapper script will always give us the right wrapper. Running gclient.py directly means that python3 would be invoked and gclient's dependencies are assumed to be installed already.

# When in a Flutter Engine checkout, this script checks what version of the Dart
|
|
# SDK the engine is pinned to, and patches the engine if there is a known patch
|
|
# that needs to be applied on the next Dart SDK roll in the engine.
|
|
#
|
|
# This script is meant to be used by 3xHEAD CI infrastructure, allowing
|
|
# incompatible changes to be made to the Dart SDK requiring a matching change
|
|
# to the Flutter Engine, without breaking the CI. The patch is associated with
|
|
# the Dart SDK version the engine is pinned so. When the engine rolls its SDK,
|
|
# then it stops applying patches atomically as there isn't a patch available yet
|
|
# for the new roll.
|
|
#
|
|
# Additionally, this script updates the flutter engine DEPS file with the
|
|
# Dart SDK dependencies.

# Usage: src/third_party/dart/tools/patches/flutter-engine/apply.sh
