Revert "[vm] Reduce size of Class objects in AOT and PRODUCT modes" This reverts commit 2852408881936600ad881cb7ee19342054fabce3. Reason for revert: failures on Flutter engine tests. Issue: https://github.com/flutter/flutter/issues/80801 Original change's description: > [vm] Reduce size of Class objects in AOT and PRODUCT modes > > This change conditionally removes certain fields from Class objects > in AOT and PRODUCT modes. > > Flutter gallery in release-sizeopt mode: > Snapshot size -0.47% (arm64), -0.44% (arm) > Heap size of snapshot objects -4.1% (arm64), -4.3% (arm) > > On a large Flutter application compiled in --dwarf-stack-traces mode: > Heap size of Class objects -26% > Heap size of all snapshot objects -3.6% > > TEST=ci > Issue: https://github.com/dart-lang/sdk/issues/44020 > Change-Id: I795c625b71558cd2f336f92fc326c36fd339cd4b > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/195700 > Commit-Queue: Alexander Markov <alexmarkov@google.com> > Reviewed-by: Ryan Macnak <rmacnak@google.com> TBR=vegorov@google.com,rmacnak@google.com,alexmarkov@google.com,sstrickl@google.com Change-Id: I0dbf1d5fc139f3654ce52f185b799c09bba66de7 No-Presubmit: true No-Tree-Checks: true No-Try: true Issue: https://github.com/dart-lang/sdk/issues/44020 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/196102 Reviewed-by: Alexander Markov <alexmarkov@google.com> Commit-Queue: Alexander Markov <alexmarkov@google.com>
Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
See LICENSE and PATENT_GRANT.

Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch).
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
There are more documents on our wiki.
The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
