prefer_null_aware_method_calls

Learn about the prefer_null_aware_method_calls linter rule.

Stable

Prefer null-aware method calls.

Details

#

Instead of checking nullability of a function/method f before calling it, you can use f?.call().

BAD:

dart 
if (f != null) f!();

GOOD:

dart 
f?.call();

Enable

#

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

analysis_options.yaml
yaml 
linter:  rules:  - prefer_null_aware_method_calls

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

analysis_options.yaml
yaml 
linter:  rules:  prefer_null_aware_method_calls: true
