[vm/aot] Disable signature shaking for 'this' of inline class members Specification of inline classes has the following rule for closurization (tear-off creation) of inline class members: > The operator == of the closurization returns true if and only if > the operand is the same object. This means that each time tear-off is taken, a new closure should be created which compares equal only to itself. This is true iff that closure has a non-empty context which captures 'this'. Signature shaking can remove 'this' parameter if it is not used and this affects equality of the tear-offs of inline class members. This change prevents that by marking 'this' parameter of inline class members as checked.

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.
