Linter warnings when importing packages within dart libs


Linter warnings when importing packages within dart libs

around this issue Your package should not contain more than one pubspec.yaml file. The lib/ folder should have only dart files and other assets, such as html, js and css files. For example, you can organize your project as follow:
code :
 my_app/
     lib/
        my_library1/
            my_library1.dart
            my_library1.html
        ...
     web/
     pubspec.yaml //you do not need to include my_library1 as a dependency here
 my_library1/
     example/
     lib/
         my_library1.dart
         my_library1.html
     pubspec.yaml
 my_app/
     lib/
         ...
     web/
     pubspec.yaml //you need to include my_library1 as a dependency here
 <link rel="import" href="../../packages/polymer/polymer.html">

I hope this helps . I think there aren't many good options to handle this. I didn't know Polymer checks this because it is perfectly valid to have a custom tag without it being a Polymer element (as in your example).
you can
code :
  - polymer:
      lint: false

like below fixes the issue In Scala 2.12 is there any difference between any of these options: , If you run scalac -Xlint:help you'll see
code :
❯ scalac -Xlint:help

This might help you It's just a warning that you're re-using the same string literal in multiple places. This can be problematic because string literals are liable to be misspelled without noticing. The solution is to use a constant instead. This is made very easy in your case, because all of the (standard) HTTP verbs are already constants exported by the http package. Just update your string literals to use the contant version instead:
code :
func (a *App) PageLogin(res http.ResponseWriter, req *http.Request) {
        switch r.Method {
            case http.MethodGet:
                // Serve the resource.
            case http.MethodPost:
                // Create a new record.
            case http.MethodPut:
                // Update an existing record.
            case http.MethodDelete:
                // Remove the record.
            default:
                // Give an error message.
        }
}
req, err := http.NewRequest("DLETE", ...)
req, err := http.NewRequest(http.MethodDlete, ...)

will help you as io specifies a prefix.
Without you can use members dart:io exports like
code :
var f = File();
var f = io.File();

Hope this helps What happens is, the class is defined in a lower part of the framework (here foundation for FlutterError)
And then higher layers of the framework reexport the content of the lower layers, using the export directive.
code :
export 'package:flutter/widget.dart';

class RaisedButton { }
