flutility 0.0.1 flutility: ^0.0.1 copied to clipboard
A new Flutter package project.
Flutter Util #
A collection of useful widgets and other stuff. All the widgets are documented. See how it works in the examples
This package contains #
- SimpleAnimatedIcon
- ScaleItemSwitch
- Logger
- RippleAnimation
Installation #
Add the package to your pubspec.yaml
file.
flutter_util: <Newest Version>
Examples #
More examples will be added soon.
Logger #
Tired of reading all these grey boring logs? Try Logger! Just create a logger somewhere in your code. You can give it a name if you want.
var logger = Logger(name: 'Logan the logger');
And now you can use it.
logger.log('Hello there');
ScaleItemSwitch #
/A widget to switch between two icons with the simple material icon transition. Like the third transition here.
The animation is controlled by the [animate] value. [firstIcon] and [secondIcon] are properties in a IconButton
so they should be some sort of icon.
If [firstIcon] or [secondIcon] are not set the other icon will just disappear. Icons are in the disabled state if they don't have there VoidCallback set.
bool animate = false;
void switchIcon() {
setState(()) {
animate = !animate;
}}
ScaleIconSwitch(
animate: animate,
firstIcon: Icon(Icons.delete_outline),
fsecondIcon: Icon(Icons.share_outlined),
onFirstPressed: switchIcon,
onSecondPressed: switchIcon,
)
