noop_primitive_operations

目录

Noop primitive operations.

This rule is available as of Dart 2.14.0.

This rule has a quick fix available.

Details

Some operations on primitive types are idempotent and can be removed.

BAD:

doubleValue.toDouble();

intValue.toInt();
intValue.round();
intValue.ceil();
intValue.floor();
intValue.truncate();

string.toString();
string = 'hello\n'
    'world\n'
    ''; // useless empty string

'string with ${x.toString()}';

Usage

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

linter:
  rules:
    - noop_primitive_operations
