Prefer putting asserts in initializer lists.

Details

#

DO put asserts in initializer lists.

BAD:

dart 
class A {  A(int a) {  assert(a != 0);  } }

GOOD:

dart 
class A {  A(int a) : assert(a != 0); }

Enable

#

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

analysis_options.yaml
yaml 
linter:  rules:  - prefer_asserts_in_initializer_lists

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

analysis_options.yaml
yaml 
linter:  rules:  prefer_asserts_in_initializer_lists: true
