#4 Flutter + Dart Tips

13. Prefer single quotes for strings

Use double quotes for nested strings or (optionally) for strings that contain single quotes. For all other strings, use single quotes.

final String name = 'Flutter And Dart Tips';
print('Hello ${name.split(" ")[0]}');
print('Hello ${name.split(" ")[2]}');

14. Set background image to your Container.

Want to set the background image to your Container? And you are using a Stack to do so? There is a better way to achieve this result. You can use decoration to set the image in the container.

Container(
  width: double.maxFinite,
  height: double.maxFinite,
  decoration: BoxDecoration(
    image: DecorationImage(
      image: NetworkImage('https://bit.ly/2oqNqj9'),
    ),
  ),
  child: Center(
    child: Text(
      'Flutter.dev',
      style: TextStyle(color: Colors.red),
    ),
  ),
),

You can provide Image according to your need, also you can use the box decoration properties to provide shape and border.

15. Check if release mode or not

You can use kReleaseMode constant to check if the code is running in release mode or not.kReleaseMode is a top-level constant from foundation.dart.

More specifically, this is a constant that is true if the application was compiled in Dart with the ‘-Ddart.vm.product=true’ flag. (from https://api.flutter.dev/flutter/foundation/kReleaseMode-constant.html)

import 'package:flutter/foundation.dart';
print('Is Release Mode: $kReleaseMode');
