Lecarvalho / dynamic_size.dart
Created December 5, 2019 08:19
A class to help in adaptation of the sizes for widgets, texts, images, etc, on different screen sizes. In my case it uses a base designWidth = 411 because this is the width for my device used for development. Check yours with your designer or in your sketch / prototype.
import 'package:flutter/material.dart';
class DynamicSize {
MediaQueryData _mediaQuery;
static const double _designWidth = 411;
DynamicSize._constructor();
static final DynamicSize instance = DynamicSize._constructor();
