E014: several-not-null-assertions

Metadata

• Code: E014
• Rule: several-not-null-assertions
• Status: Stable since v0.0.1
• Quick fix: always available

What it does

Detects repeated not-null assertions like foo!!.

Why is this bad?

Repeating ! is redundant: after the first not-null assertion the value is already non-null.

Example

val x = foo!!;
E014: several not-null assertions in a row

Use instead:

val x = foo!;
