scaff | Scaffold Generator for Dart and Flutter
scaff is a simple command-line utility for generating Dart and Flutter components from template files. It is a very tedious job to keep replicating the boilerplate codes every time you try to add a new component in your app. Using scaff, you can generate dart or flutter components from the custom-defined templates. You can even add template schemes to the component directories and files for easy and flexible scaffolding.​Get the package from: https://pub.dev/packages/scaffGitHub: https://github.com/ganeshrvel/pub-scaff

Design question
How would you create a hollow circle that draws on the screen when the user sees it. If a percentage is given I want the circle to draw according to that. So if .50 was input, I want the circle to draw in until it's 180 degrees - so a semicircle.Thanks

How to change PageView physics dynamically with setState?
I am trying to create a way to slide to my second screen ONLY from the Home screen of my Child widget. This means if I am on the Search, Profile, etc. screen, the Physics of the PageView will switch to NeverScrollableScrollPhysics so that the second screen in the PageView can only be navigated to from the Home Screen.This is the DualScreen Class that is handing the PageView and controlling the switching between the two screens. The Physics is NOT rebuilding when I grab a new Index and change the _mainScreenCurrentIndex value in setState with the _getMainIndex callback function.

import 'package:flutter/material.dart'; import 'main_screen.dart'; import 'transaction_screen.dart'; class DualScreen extends StatefulWidget { @override _DualScreenState createState() => _DualScreenState(); } class _DualScreenState extends State<DualScreen> { @override Widget build(BuildContext context) { int _mainScreenCurrentIndex = 0; void _getMainIndex(int index) { setState(() { _mainScreenCurrentIndex = index; }); print(_mainScreenCurrentIndex); } final _pageController = PageController( initialPage: 0, ); return Scaffold( body: PageView( controller: _pageController, children: <Widget>[MainScreen(parentAction: _getMainIndex,), TransactionScreen()], pageSnapping: true, physics: _mainScreenCurrentIndex == 0 ? ClampingScrollPhysics() : NeverScrollableScrollPhysics())); } } 

This is the MainScreen that I am grabbing the index from.

import 'package:flutter/material.dart'; import 'home_screen.dart'; import 'search_screen.dart'; import 'qr_screen.dart'; import 'wallet_screen.dart'; import 'profile_screen.dart'; class MainScreen extends StatefulWidget { final void Function(int index) parentAction; MainScreen({this.parentAction}); @override _MainScreenState createState() => _MainScreenState(); } class _MainScreenState extends State<MainScreen> { int _currentIndex = 0; final List<Widget> _screens = <Widget>[ HomeScreen(), SearchScreen(), QrScreen(), WalletScreen(), ProfileScreen() ]; void onTabTapped(int index) { setState(() { _currentIndex = index; }); widget.parentAction(index); } @override Widget build(BuildContext context) { return Scaffold( backgroundColor: Color(0xfffafafa), body: _screens.elementAt(_currentIndex), bottomNavigationBar: BottomNavigationBar( showSelectedLabels: false, showUnselectedLabels: false, items: [ BottomNavigationBarItem( icon: Icon( Icons.home, color: _currentIndex == 0 ? Colors.amber : Colors.black, ), title: Text( 'Home', style: TextStyle(color: Colors.black), ), ), BottomNavigationBarItem( icon: Icon( Icons.search, color: _currentIndex == 1 ? Colors.amber : Colors.black, ), title: Text( 'Search', style: TextStyle(color: Colors.black), ), ), BottomNavigationBarItem( icon: _currentIndex == 2 ? Image.asset('assets/images/qr-code-2.png', height: 25, width: 25) : Image.asset('assets/images/qr-code.png', height: 25, width: 25), title: Text( 'Scan', style: TextStyle(color: Colors.black), )), BottomNavigationBarItem( icon: Icon(Icons.credit_card, color: _currentIndex == 3 ? Colors.amber : Colors.black), title: Text( 'Wallet', style: TextStyle(color: Colors.black), ), ), BottomNavigationBarItem( icon: Icon( Icons.person, color: _currentIndex == 4 ? Colors.amber : Colors.black, ), title: Text( 'Profile', style: TextStyle(color: Colors.black), )) ], type: BottomNavigationBarType.fixed, onTap: onTabTapped, currentIndex: _currentIndex, )); } }

Convert Scikit-learn models to pure Dart code for on-device, offline ML using m2cgen Python tool with zero dependencies.
Disclaimer: I did not create m2cgen. I am only in the process of adding functionality to the project to convert sklearn models to Dart (my fork). My pull request is awaiting review, but I wanted to get this in front of some Flutter dev eyes asap. Big thanks to the contributors of the project!m2cgen is a great tool for allowing the conversion of sklearn models into native code, which allows sklearn capabilities almost anywhere. I think the number of on-device ML solutions for Flutter is bit lackluster, but I am excited to see how Google further implements Tensorflow Lite functionality into the framework.For relatively simple use cases and models, the less exciting approaches (linear/logistic regression, decision trees, etc.) actually are preferred due to simplicity and explainability. It is hard to argue for using a complex, resource-hungry neural network when a quick random forest model gets close to the same accuracy. On-device models are growing in popularity due to being completely private, offline, and more secure than sending data over the wire. Even with an absolute beast of a model hosted on a server, network latency could kill performance altogether, especially if the user needs to go offline and still use your app. List of supported models with m2cgen.This library opens up many of the capabilities of sklearn's powerful library for many languages. I hope that the soon to be added Dart support will come in handy for at least one of you in your various projects.I would appreciate if you could take a look at the pull request and offer any insight into the most effective way to structure the Dart code. It is pretty straightforward though.If you want to try it out before it gets merged into the main repo, you can check out my fork. It is working based on my testing. You can see a quick example in this jupyter notebook gist.I am happy to discuss in the comments! Happy fluttering.
