Which channel do I use in Flutter SDK?

From the Flutter wiki:


Flutter has the following channels, in increasing order of stability:

master

The current tip-of-tree, absolute latest cutting edge build.
Usually functional, though sometimes we accidentally break things.

dev

Previously known as alpha, this is the latest fully-tested build.
Usually functional, but see Bad Builds for a list of known "bad" dev
builds.

beta

Every few weeks, we pick the "best" dev build of the previous
month or so, and promote it to beta. These builds have been tested
with our codelabs.

Eventually we will also have a release build, which will be the best beta build of the previous year or so, but we haven't yet reached a quality level that we are sufficiently happy with to use this label yet.


So, use whichever channel you feel comfortable with, meets your needs and/or has whichever fixes in it you need. Start with beta and go from there.

Meaning of `{}` for return expression

-
15 1 I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type? ...

Get current scroll position of ScrollView in React Native

-
Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native? So something like: <ScrollView horizontal={true} pagingEnabled={true} onScrollAnimationEnd={() => { // get this scrollview's current page or x/y scroll position }}> this.state.data.map(function(e, i) { <ImageCt key={i}></ImageCt> }) </ScrollView> Try. <ScrollView onScroll={this.handleScroll} /> And then: handleScroll: function(event: Object) { console.log(event.nativeEvent.contentOffset.y); }, Disclaimer: what follows is primarily the result of my own experimentation in React Native 0.50. The ScrollView documentation is currently missing a lot of the information covered below; for instance onScrollEndDrag is completely undocumented. Since everything here relies upon undocumented behaviour, I can unfortunately make no promises that this information will remain correct a ...
