| * @assertion To infer the type of element: |
| * |
| * If element is an expressionElement with expression e1: |
| * ... |
| * If P is Set<Ps> then the inferred set element type of element is the inferred |
| * type of the expression e1 in context Ps. |
| * |
| * @description Checks that if P is Set<Ps> then the inferred set element type |
| * of element is the inferred type of the expression e1 in context Ps. |
| * |
| * See Issue 43139 evaluation: With null safety, doing 1 + x in a double context |
| * will figure out that the only way int + something is going to be a double is |
| * if the something is a double, so it will give x a context type of double. |
| * Then double x = 1 + 1; will convert the latter 1 to a double literal, and the |
| * result becomes a double. So, there is not compile error here with nnbd, and |
| * it's a compile error without nnbd. |
