Anna Gringauze 6f16174d56 remove private fields and modules calculations from expression compiler
- Remove collecting private fields from scope calculation
  We only need to collect the fields from the evaluated
  expression and they are already collected separately.

- Correct private fields calculation
  Currently, library names are assumed to be the same as the module,
  which creates redefinitions of library variable in produced Javascript
  code, and exceptions in chrome for modules that contain more than one
  library.
  The actual fix will come from making DDC incremental by storing more
  information, for now make a best effort to compute correct names for
  library variables from the module data that expression compiler
  receives from chrome. The following code will be produced to calculate
  private symbols _pf1 (from lib1, module1) and _pf2
  (from lib2 module1):

  let lib1 = require('module1.dart').lib1;
  let lib2 = require('module1.dart').lib2;

  let _pf1 = dart.privateNames(lib1, '_pf1');
  let _pf2 = dart.privateNames(lib2, '_pf2');

  Note that this seems to work even if the current breakpoint is inside
  the define statement for lib1, and the lib1 symbol is not exported
  yet.

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).
