flutter/flutter

Flutter makes it easy and fast to build beautiful apps for mobile and beyond.

Container itself is a bit of a beginner tool. It's very useful to give beginner a foothold into the system, but most developers end up using the component pieces directly as they become more advance because that's the more flexible/powerful approach

Padding tends to be the stepping stone in that direction

hence the long design discussion in the docs for Padding

@blehn

gotcha, thanks

@donnyv

@eseidel do you have a sample anywhere with that?

Eric Seidel

@eseidelGoogle

@donnyv I'm forgetting the question? Which sample are you looking for? :)

@jacoplane

@cortexdesign I presume the Firebase plugin will work soon since there's an event about Flutter & Firebase in less than a month at I/O: https://events.google.com/io/schedule/?section=may-19&sid=496d01fb-2139-4fd6-84b2-e585d1a20e61

@eseidelGoogle adding a WebView

Hadrien Lejard

@lejard-h

@donnyv I am working on a webview plugin, I hope it will be available soon (at least for Android), but to be sure what are your needs ? Having a fullscreen web view in a different activity or, a full screen web view with flutter widgets on top ?

Donny Velazquez

@donnyv

Having a full screen WebView in its own activity is fine. I can always add additional UI elements using html. I know you can't add flutter widgets right now but is there a way for javascript code in a WebView to reach back out to Dart code?

it appears to me that it's impossible to change a TextEditingController from its listener

is this expected or a bug?

Eric Seidel

@eseidelGoogle

@christian-lefty @abarth would know. Or you can ask on stackoverflow.com/questions/tagged/flutter if he's not around

@donnyv I don't currently have an example of adding a webview, but I'll add it to the list of samples we should provide

Adam Barth

@abarth

I think it should be possible

what goes wrong?

Does a GridView require GridTiles as children?

blehn

@blehn

Ah, I think I found some older discussion about this. I'm trying to put a GridView inside a ScrollView, but it's not working for some reason. I don't need the GridView to scroll, but I'd prefer to use it instead of a Row because (a) I want it to flow to multiple rows if there are enough children, and (b) GridView has properties for item spacing that Row doesn't have

Is there a different class I should be using?

Adam Barth

@abarth

You might want Wrap

GridView does not require its children to be GridTiles

taylorren

@taylorren

Hello

In a Fltter app's Stateful widget, where is the right place to put a call to fetch remote API?

blehn

@blehn

@abarth shrinkWrap: true on the GridView seems to fix my issue. Is Wrap a better solution?

Adam Barth

@abarth

@blehn depends if you want the children to line up vertically as well as horizontally

if you do, grid is a good choice

blehn

@blehn

yeah, I do

Adam Barth

@abarth

if you want them to line up horizontally but not necessarily vertically, then wrap is a good choice

then I'd go with Grid

GridView

blehn

@blehn

k thanks... and is shrinkWrap the right property to use to render a GridView within a ScrollView?

Adam Barth

@abarth

yep

Hi there

A quick question, I am looking at the Flutter example and noticed this section:

child: new RichText(
            text: new TextSpan(
              children: <TextSpan>[
                new TextSpan(
                  style: aboutTextStyle,
                  text: "Flutter is an early-stage, open-source project to help "
                  "developers build high-performance, high-fidelity, mobile "
                  "apps for iOS and Android from a single codebase. This "
                  "gallery is a preview of Flutter's many widgets, behaviors, "
                  "animations, layouts, and more. Learn more about Flutter at "
                ),
                new LinkTextSpan(
                  style: linkStyle,
                  url: 'https://flutter.io'
                ),
                new TextSpan(
                  style: aboutTextStyle,
                  text: ".\n\nTo see the source code for this app, please visit the "
                ),
                new LinkTextSpan(
                  style: linkStyle,
                  url: 'https://goo.gl/iv1p4G',
                  text: 'flutter github repo'
                ),
                new TextSpan(
                  style: aboutTextStyle,
                  text: "."
                )
              ]
            )
          )

I tried to copy that code segment to my program but was prompted with this error:

The constructor returns type 'dynamic' that isn't of expected type 'TextSpan'

What is going wrong here?

Marian

@cortexdesign

@jacoplane sounds good :)

Günter Zöchbauer

@zoechi

never heard of a constructor returning dynamic :D

taylorren

@taylorren

@zoechi I know it is funny. But that segment of code runs fine in the demo app

Am I missing any import?

OIC... My bad. Solved.

Marian

@cortexdesign

@taylorren is LinkTextSpan inherit from TextSpan?

taylorren

@taylorren

@cortexdesign Yes, I am missing this class declaration.
