Analysis options: #
You can use the same analysis options which this package uses by simply including them in your analysis_options.yaml file:
include: package:fleasy/analysis_options.yaml
copied to clipboard
They are based on:
package:flutter_lints (therefore also package:lints)
my favorite lint rules which are not present in package:flutter_lints
For more details, have a look at the analysis_options.yaml file here.
