Framelayout alternative in flutter

-
I want to add a Flutter Container in top of another Container and top container will be transparent. Basically I do that in native Android using FrameLayout. How to implement this in Flutter?

Stack is most likely what you want.

Stack allows to put widgets on the top of others however you like. And, combined with Positioned, have custom positions.

Let's draw a real frame in flutter :



Stack(
alignment: Alignment.center,
children: <Widget>[
Container(
width: 200.0,
height: 300.0,
decoration: BoxDecoration(
color: Colors.black12,
border: Border.all(
color: Colors.black,
width: 3.0,
),
),
),
Container(
width: 100.0,
height: 100.0,
color: Colors.blue,
),
Positioned(
bottom: 10.0,
right: 10.0,
child: Card(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Text("Title"),
),
),
)
],
),

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 ...
