## 1.12.0
### Language changes
* Null-aware operators
* `??`: if null operator. `expr1 ?? expr2` evaluates to `expr1` if not `null`, otherwise `expr2`.
* `??=`: null-aware assignment. `v ??= expr` causes `v` to be assigned `expr` only if `v` is `null`.
* `x?.p`: null-aware access. `x?.p` evaluates to `x.p` if `x` is not `null`, otherwise evaluates to `null`.
* `x?.m()`: null-aware method invocation. `x?.m()` invokes `m` only if `x` is not `null`.
### Core library changes
* `dart:async`
