Previously, https://github.com/flutter/flutter/pull/100271 enabled
building universal macOS binaries by default, but included a bug causing
the arm64 App.framework to be built such that the TEXT section
containing the app instructions built by gen_snapshot incorrectly
contained x86_64 instructions rather than arm64 instructions.
When building macOS (and iOS) apps, Flutter builds them in three
components:
* The Runner application: built by Xcode
* The bundled App.framework: built from assembly code generated by
gen_snapshot from the application's Dart sources.
* The bundled FlutterMacOS.framework: built as part of the engine build
and packaged by copying the distributed binary framework from our
artifacts cache.
Building App.framework consists of the following steps:
* For each architecture, invoke gen_snapshot to generate
architecture-specific assembly code, which is then built to object
code and linked into an architecture-specific App.framework.
* Use the `lipo` tool to generate a universal binary that includes both
x86_64 and arm64 architectures.
Previously, we were building architecture specific App.framework
binaries. However, for all architectures we were (mistakenly) invoking
the general `gen_snapshot` tool (which emitted x64 instructions, and
which is now deprecated) instead of the architecture-specific
`gen_snapshot_x86` and `gen_snapshot_arm64` builds which emit
instructions for the correct architecture.
This change introduces a small refactoring, which is to split the
`getNameForDarwinArch` function into two functions:
* `getDartNameForDarwinArch`: the name for the specified architecture as
used in the Dart SDK, for example as the suffix of `gen_snapshot`.
* `getNameForDarwinArch`: the name for the specified architecture
as used in Apple tools, for example as an argument to `lipo`. For
consistency, and to match developer expectations on Darwin platforms,
this is also the name used in Flutter's build outputs.
Issue: https://github.com/flutter/flutter/issues/100348
* fix deprecated_new_in_comment_reference for `material` library
in a future version of the SDK, these will be flagged, fix them now
* Update pubspec.yaml
* [web] roll Chromium dep to 96.2
Roll Chromium 96.2.
This is the second attempt to roll it. The previous attempt
(https://github.com/flutter/flutter/pull/99725) failed due to a LUCI
cache issue.
* cache-bust CIPD dependency by changing its name
* specify chrome_and_driver version in canvaskit tests
* fix CRC corruption in kTransparentImage
This changes the default build architectures for Flutter macOS apps to
x86_64 and arm64. Previously, we manually excluded arm64 builds via the
EXCLUDE_ARCHS Xcode setting in Flutter's generated xcconfig file. This
eliminates setting EXCLUDE_ARCHS during the build and updates the
default architectures in the tool and in the macos_assemble.sh wrapper.
