1. Naming Conventions

Item	Case & Naming
Files & Packages	lowercase_with_underscores
Import Prefixes	lowercase_with_underscores
Classes & Enums	UpperCamelCase
Typedefs & Type Parameters	UpperCamelCase
Other Identifiers	lowerCamelCase
Constants	SCREAMING_CAPS

2. Imports Ordering

Order your imports in the following order, separated with a blank line and sorted alphabetically within each section:

1. dart: imports.
2. package: imports.
3. Relative imports.

import 'dart:async';
import 'dart:html';

import 'package:bar/bar.dart';
import 'package:foo/foo.dart';

import 'util.dart';

3. Programming Practices

3.1. Never Use new Keyword

The new keyword is optional in dart, so just don't use it.

var x = new Foo();   // bad
var y = Foo();       // good

3.2. Always Use Relative Imports

import 'package:tazkrtak/util/foo.dart';   // bad
import '../util/foo.dart';                 // good

4. Formatting

4.1. Always Use Trailing Commas

Using trailing commas helps the automatic formatter to insert an appropriate amount of line breaks for Flutter-style code.

// bad
ButtonTheme(height: 56, child: Text('foo', style: TextStyle(fontSize: 20)));
                                                                        ^^^
// good
ButtonTheme(
  height: 56,
  child: Text(
    'foo',
    style: TextStyle(
      fontSize: 20,
    ),            ^
  ), ^
); ^
