Flutter lower dart version

-
I'm getting the following error due to Dart version of my flutter setup when I run the flutter get packages command:


[project_name] flutter packages get Running "flutter packages get"
in project_name...
The current Dart SDK version is
2.1.0-dev.0.0.flutter-be6309690f.

Because project depends on intl_translation >=0.14.0+1 <0.17.0 which
requires SDK version >=1.12.0 <2.0.0, version solving failed. pub get
failed (1) exit code 1


My framework version:


Flutter 0.6.0 • channel beta • https://github.com/flutter/flutter.git
Framework • revision 9299c02cf7 (2 weeks ago) • 2018-08-16 00:35:12 +0200
Engine • revision e3687f70c7
Tools • Dart 2.1.0-dev.0.0.flutter-be6309690f


I would like to learn if there's some kind of command to lower dart-sdk version of the flutter framework, thanks in advance.

In the Flutter install directory execute

git checkout v"0.5.0" // for example


You can check which versions are available in the Flutter GitHub repository https://github.com/flutter/flutter

You can only change the Dart version if you change to a Flutter version that contains the desired Dart version.

Change the dependency to

dev_dependencies:
intl_translations: ^0.17.0


Add following dependency in pubspec.yaml file

version: 1.0.0+1

environment:
sdk: ">=2.0.0-dev.68.0 <3.0.0"

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 ...
