For example:

rules:
- id: taint
  languages: [dart]
  message: "tainted data reached sink"
  severity: ERROR
  mode: taint
  pattern-sources:
    - pattern: |
        (UserData $FOO).getData()
  pattern-sinks:
    - pattern: |
        sink(...)
void performQuery(UserData bad, OtherData good) {

  x = bad.getData();
  // ruleid: taint
  sink(x);

  y = good.getData();
  // ok
  sink(y);
}
