Say you have a class method like this:
```
class Bar {
/*offset a*/ void /*offset b*/ qux() {
/*offset c*/ print("hello");
}
}
```
Lets also say that this method is run.
This will mark offset a and offset c as hits.
Offset b does not exist in coverage terms.
Now say you have an extension mehod like this:
```
extension Foo on Bar {
/*offset a*/ void /*offset b*/ baz() {
/*offset c*/ print("hello");
}
}
```
Lets also say that this method is also executed.
This will mark offset a and offset c as hits.
Offset b does not exist in coverage terms for this method.
Because extension methods are special though we create a special tearoff for
it. Lets say we didn't execute that one.
The tearoff method - before this CL - had offset b on positions that caused
the position to exist in coverage terms, and as the method wasn't executed
this would make it a miss.
This CL fixes the issue by setting the offsets on the tearoff that before
introduced offset b to offset a instead.

Front end for Dart
This package provides a low-level API for use by compiler back ends that wish to implement the Dart language. It is intended for eventual use by dev_compiler, dart2js, and the Dart VM. In addition, it will share implementation details with the analyzer package--this will be accomplished by having the analyzer package import (and re-export) parts of this package's private implementation.
End-users should use the dart analyze
command-line tool to analyze their Dart code.
Integrators that want to write tools that analyze Dart code should use the analyzer package.
Note: A previous version of this package was published on pub.dev. It has now been marked DISCONTINUED as it is not intended for direct consumption, as per the notes above.
