This change is needed for compatibility with the Flutter Engine's use of a new Android NDK. The new Android NDK includes a new clang toolchain which does a better job of classifying various contributors to a binary's size, but which fails the compatibility checks in the script. The intention of the compatibility checks is to exclude versions of tooling that are too old not versions that are too new. The compatibility check is also redundant with failure modes later in the script. To avoid breaking any usage of this script in the Dart tree, however, the check is retained by this change, and instead a flag is added that skips it. This is preferable to expanding on the questionable use of regular expressions that implement the check to capture the strings emitted by a continually updating toolchain.

Dart
A client-optimized language for fast apps on any platform
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).
