Documenting tips Programming is sometimes 60% coding and 40% documenting. So it's very useful to know about documenting tips. If you are having trouble coming up with useful documentation, here are some useful tips. Avoid checking in comments that ask questions // BAD: // What should this be? // This is a workaround. // GOOD: // According to this specification, this should be 2.0, but according to that // specification, it should be 3.0. We split the difference and went with // 2.5, because we didn't know what else to do. // TODO(username): Converting color to RGB because class Color doesn't support // hex yet. See http://link/to/a/bug/123 Avoid useless documentation // BAD: /// The background color. final Color backgroundColor; /// Half the diameter of the circle. final doub

Image
Introduction In this article I'm going to explain you about how image with round corners and splash effect is created using Flutter widgets. Before doing some coding, let's see how images are loaded in Flutter and what the splash effect means. Images in flutter In flutter apps, we can load images from network, assets (App resources) or from the file system. Loading images from network is very easy task in flutter using Image.network constructor. Image.network( 'https://raw.githubusercontent.com/flutter/website/master/src/_includes/code/layout/lakes/images/lake.jpg', ) If you want to load images from network and cache it for offline usage, you can use CachedNetworkImage widget. You need to add cached_network_image dependency to use it. Click here to see installation instructions. CachedNetworkImage( placeholder: CircularProgressIndicator(), imageUrl: '

AVR Analog Comparator

Introduction AVR Analog comparator can be used to compare two analog inputs. The Analog Comparator compares the input values on the positive pin AIN0 and negative pin AIN1. When the voltage on the positive pin AIN0 is higher than the voltage on the negative pin AIN1, the Analog Comparator Output, ACO is set. the comparator can trigger a separate interrupt, exclusive to the Analog Comparator. We can select Interrupt triggering on comparator output rise, fall or toggle. Following is a block diagram of comparator and it's logic. Analog Comparator block diagram Registers ACSR (Analog Comparator Control and Status Register) is an 8-bit register which contains configuration bits for Analog Comparator. ACSR (Analog Comparator Control and Status Register) ACIS0, ACIS1 (Analog Comparator Inter
