Avoid using unnecessary statements.

Details

AVOID using unnecessary statements.

Statements which have no clear effect are usually unnecessary, or should be broken up.

For example,

BAD:

dart
myvar; list.clear; 1 + 2; methodOne() + methodTwo(); foo ? bar : baz; 

Though the added methods have a clear effect, the addition itself does not unless there is some magical overload of the + operator.

Usually code like this indicates an incomplete thought, and is a bug.

GOOD:

dart
some.method(); const SomeClass(); methodOne(); methodTwo(); foo ? bar() : baz(); return myvar; 

Enable

To enable the unnecessary_statements rule, add unnecessary_statements under linter > rules in your analysis_options.yaml file:

analysis_options.yaml
yaml
linter:  rules:  - unnecessary_statements 

If you're instead using the YAML map syntax to configure linter rules, add unnecessary_statements: true under linter > rules:

analysis_options.yaml
yaml
linter:  rules:  unnecessary_statements: true
