This reverts commit83d2aaa072. Reason for revert: Want to reenable const-update-2018 by default. Original change's description: > Revert "[dart] Enable constant-update-2018" > > This reverts commit9bbd3192f4. > > Reason for revert: Reverting enabling of constant-update-2018 by default as some blocking issues were found that are breaking Flutter and preventing rolls of Dart into Flutter. Once the blocking issues are addressed and fixed this CL will be relanded. > > Original change's description: > > [dart] Enable constant-update-2018 > > > > Change-Id: Ib3942b4f6e336a02826305d9f81839333a5464a0 > > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/106943 > > Reviewed-by: Vyacheslav Egorov <vegorov@google.com> > > Commit-Queue: Vyacheslav Egorov <vegorov@google.com> > > TBR=paulberry@google.com,vegorov@google.com,athom@google.com,vsm@google.com,aadilmaan@google.com > > # Not skipping CQ checks because original CL landed > 1 day ago. > > Change-Id: I5796881412cec464f450ff3894ca253c58edc4a2 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/109308 > Reviewed-by: Siva Annamalai <asiva@google.com> > Reviewed-by: Vijay Menon <vsm@google.com> TBR=paulberry@google.com,vegorov@google.com,athom@google.com,vsm@google.com,asiva@google.com,aadilmaan@google.com # Not skipping CQ checks because original CL landed > 1 day ago.

|
# Experimental features are described in docs/process/experimental-flags.md
|
|
# (Despite the name, they are not really intended for experiments.)
|
|
# They are intended to enable new features or enhancements that are being
|
|
# developed and are not yet shipped. Experimental feature flags are expected
|
|
# to be relatively short-lived.
|
|
#
|
|
# ### Code Generation
|
|
#
|
|
# When you change this file, run the following to update analyzer and kernel:
|
|
#
|
|
# analyzer:
|
|
# dart pkg/analyzer/tool/experiments/generate.dart
|
|
#
|
|
# kernel:
|
|
# pkg/front_end/tool/fasta generate-experimental-flags
|
|
#
|
|
# ### Overview
|
|
#
|
|
# Each entry in this map corresponds to an experiment,
|
|
# and contains the following parts:
|
|
#
|
|
# 1. help: (required text)
|
|
# A human readable description of the experiment.
|
|
#
|
|
# 2. enabledIn: (optional #.#)
|
|
# The Dart SDK version (<major>.<minor>) in which the experiment is shipping.
|
|
#
|
|
# If this field is specified, then the experiment is enabled regardless of
|
|
# the actual version of the SDK. If this field is omitted, then the
|
|
# experiment is disabled by default, but may be enabled by specifying the
|
|
# flag on the command line. (e.g. --enable-experiment=non-nullable)
|
|
#
|
|
# A version less than than this version may be specified in a .packages file
|
|
# or in a library language version override (e.g. // @dart = 2.1)
|
|
# to disable this feature. For more on library language version override, see
|
|
# https://github.com/dart-lang/language/blob/master/accepted/future-releases/language-versioning/language-versioning.md
|
|
#
|
|
# 3. expired: (optional boolean)
|
|
# If true, then the experiment can no longer be enabled by specifying the
|
|
# flag on the command line, and the corresponding entry is slated for
|
|
# eventual removal from this file. If this field is omitted, then 'expired'
|
|
# is considered to be false.
|
|
#
|
|
# Using the above fields, experiments pass through several states:
|
|
#
|
|
# Disabled:
|
|
# When an experiment is first added to this file, the 'enabledIn' and
|
|
# 'expired' fields are omitted and the experiment is disabled by default,
|
|
# but may be enabled by specifying the flag on the command line.
|
|
# The implementation teams begin building support for the feature,
|
|
# guarded by the flag. Users can enable the flag and begin to try out
|
|
# the feature as it is being developed.
|
|
#
|
|
# Shipped:
|
|
# When an experiment is shipped, then the 'enabledIn' field is added
|
|
# indicating which version of the SDK contains this new language feature.
|
|
# At this point, specifying the flag on the command line has no effect because
|
|
# the experiment is enabled by default and cannot be disabled.
|
|
#
|
|
# Retired or Rejected:
|
|
# At some point, the 'expired' field is added to the experiment indicating
|
|
# that the flag is to be retired if the experiment has shipped or that the
|
|
# entire experiment was rejected if the experiment has not shipped. It also
|
|
# indicates that the corresponding entry is slated for eventual removal
|
|
# from this file. Users specifying this flag on the command line should receive
|
|
# a warning that the experiment has been retired or rejected, but the tool
|
|
# should continue to run.
