Installation
- Add
circular_ui_navigator: 1.0.0to yourpubspec.yaml. - Run
flutter pub get
This package requires Dart SDK version 2.19.0 or above to function properly.
Please note that only SVG assets are supported for icons, as they are a highly compatible cross-platform solution. While this should be sufficient for most projects, please be aware that other icon types are not currently supported.
Usage
To use the widget in your project, add the following import statement to the top of the file where you intend to use it:
import 'package:circle_ui_navigator/circle_ui_navigator.dart';
Then, use CircleNavigatorConfig in place of a widget. You can customize all of the parameters shown below, and a few more.
import 'dart:math';
import 'dart:ui';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:circle_ui_navigator/circle_ui_navigator.dart';

Additional information
If you find a package relevant or have learned something from it, please do not hesitate to contact me or like it 🙂 Also, please raise any issues you have here on GitHub
I have found two issues that may impact your use of the package:
- If the animationDuration and backgroundAnimationDuration parameters represent different time values, the onCloseAnimationComplete function is called twice. Usually, the first call causes the app to leave the screen, which is fine.
- Some users may want to turn off animations entirely. If it applies to you, please let me know so that I can improve the package.
Dependencies
I tried to keep the project as minimalistic as possible. So its pubspec keeps only:
equatable: ^2.0.5
flutter_svg: ^2.0.2
