Lasse R.H. Nielsen e85042b403 Allow error test expectations to omit the implicit line.
Error tests with explicit line/column markers, like
 [error line 123, column 456]
currently require both "line" and "column".
All existing occurrences of `[error line 123, column 456]` always
refer to the most recent non-comment line *just like* the `// ^^` lines,
so omitting the line, and having the most recent non-comment line
as the *default* line, seems reasonable.

This CL makes the line optional, the new format without a "line" entry
will be just `[error column 456]`.

This allows files to change the number of lines in the code without
invalidating any later expectations.
(Or, say, remove a comment line at the top of the file!)

Omits the line entry by default when writing/updating expectations.

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).
