after I write my posts in my application, my photo and date center the text. I need to pin the photo and date to the beginning. What should I do for this?
............................................................................................................................................................................................
child: Row( children: [
Padding(
padding: EdgeInsets.only(top: 15),
child: CircleAvatar(
radius: 20,
backgroundImage: NetworkImage(
userData['photoUrl'],
),
),
),
Expanded(
child: Padding(
padding:
EdgeInsets.only(left: 8, top: 20),
child: Container(
child: Column(
mainAxisSize: MainAxisSize.min,
crossAxisAlignment:
CrossAxisAlignment.start,
children: [
Text(
userData['username'],
style: TextStyle(
fontWeight:

),
Container(
width: double.infinity,
padding: const EdgeInsets.only(
top: 8,

child: RichText(
text: TextSpan(

children: [
TextSpan(
text:
' ${(snap.data()! as dynamic)['description']}',
),

),
),
),

),
),
),
),
Container(
padding:
EdgeInsets.symmetric(vertical: 4),
child: Text(
DateFormat.yMd().format(

.toDate(),
),
style: const TextStyle(
fontSize: 15,
color: secondaryColor,
),
),
),
child: Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
In your Row, set crossAxisAlignment: CrossAxisAlignment.start. This will cause the Row's children to be aligned at the top of the row.
Why does the 1st two work but not the 3rd?? what's the alternative to add vertical divider with height that stretch to the max height of the row?
These 2 works
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
// crossAxisAlignment: CrossAxisAlignment.stretch,
children: [
Container(
child: Text('Kicukiro'),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
)
],
)
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
// Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
this does not work
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: Text('Kicukiro'),
),
),
Container(width: 1,color: Colors.black,height: double.infinity,),
Expanded(
child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text('Kicukiro'),
),
)
],
)
Test this and it will work
IntrinsicHeight(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(
child: Container(
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
Container(color:Colors.black, width: 1),
Expanded(
child: Container(
padding: const EdgeInsets.symmetric(horizontal: 10),
child: const Text("Kicukiro", style: TextStyle(fontSize: 52),)),
),
],
),
),
In the last screenshot please add the Container under an Expanded widget. Use children property under Row widget.
Here is an example code
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 5,
child: Padding(
padding: EdgeInsets.all(10.0),
child: Center(
child: Text(
'This is question',
style: TextStyle(
fontSize: 25.0,
color: Colors.white,
),
),
),
),
),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.green,
child: Text(
'True',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
Expanded(
child: Padding(
padding: EdgeInsets.all(10.0),
child: FlatButton(
//textColor: Colors.white,
color: Colors.red,
child: Text(
'False',
style: TextStyle(color: Colors.white, fontSize: 20.0),
),
onPressed: () {},
),
)),
]
The third is true, in fact, its existence in an SingleChildScrollView has created a problem
It is fixed by putting SizedBox in Row and giving it height
The reason for this problem is the size of the height of the container, which is determined by double.infinity and due to its presence in an SingleChildScrollView, it continues indefinitely and an error was created.
SingleChildScrollView(
child: SizedBox(
height: 250,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Expanded(child: Container(child: Text("Kicukiro"))),
Container(
width: 1,color: Colors.black,height: double.infinity,
),
Expanded(child: Container(
padding: EdgeInsets.symmetric(horizontal: 10),
child: Text("Kicukiro"))),
],
),
),
),
I have an app that has a bottomappbar with a textformfield, but when the user tries to insert data there the keyboard hides the text being typed.
I tried "resizeToAvoidBottomInset: true" and didnt worked, also tried to put a SingleChildScrollView on the body of the app and got "RenderBox was not laid out: RenderRepaintBoundary#32f0a relayoutBoundary=up1 NEEDS-PAINT 'package:flutter/src/rendering/box.dart': Failed assertion: line 1785 pos 12: 'hasSize'".
I need a way to make the bottom part "expand" to the top of the keyboard when the user is typing or a way to show in the screen the text that is being typed.
How can I solve that? I have tried many ways and nothing seems to work.
The structure of my app is:
The code:
Widget build(BuildContext context) {
return Scaffold(

use MediaQuery.of(context).viewInsets.bottom and add it to your bottom navigation height

I'm kinda a loser when it comes to formatting and I've come to the conclusion I need a little guidance/advice. I have a ListView populated with cards that display data in them. Above this ListView I have the titles for the data in the ListView. Along with a search bar, but that shouldn't affect much. I'm having issues making the titles stay aligned with the data in the cards below, especially when switching between different devices since the screen size changes. What is the best way to do this? Any help and/or advice is highly appreciated!
This is an image of how it looks currently
This is the current code. I'm using a combination of flex and expanded for most of my formatting for moving the data & titles around.
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey[200],
appBar: PreferredSize(
preferredSize: Size.fromHeight(95.0),
child: AppBar(
automaticallyImplyLeading: false, // hides leading widget
flexibleSpace: DataAppBar(onChanged: (newValue) {
setState(() {
newValue = newValue;
});
}),
),
),
body: StreamBuilder<dynamic>(
stream: DataDBProvider.dataDB.getData(),
builder: (context, snapshot) {
if (!snapshot.hasData) {
return Center(
child: CircularProgressIndicator(),
);
}
List data = snapshot.data;
return Column(children: <Widget>[

))
]);
}));
}
So you are adding extra padding in your elements in the listview that you need to add to the titles:
padding:
EdgeInsets.only(left: 6), // add margin to accomplish offsetting the labels the same as the items
So now in the titles you can add either padding or margin for 8 to the left. This only applies to the first two though. So for the final one you can do this:
Flexible(
flex: 2,
child: Container(
alignment: Alignment.end, // changed from center to end
margin: EdgeInsets.only(right:8), // add the right margin
child: Text(
"Amount",
maxLines: 1,
style: TextStyle(
color: Colors.green, fontFamily: 'Montserrat'),
also just a friendly piece of advice is that you are making this a whole lot more complicated on your self than needed. The above answers your question but I would consider trying to clean up your code so future questions/problems are easier to identify.
I have this chat item similar to what you see on WhatsApp.
This is what I have so far.

The list view is part of the body of a scaffold.
Currently only the middle part of this is the issue. And by issue I mean it is not flexing all the way. The right hand side where it says 12:02 should only expand if it has to otherwise minimum size should be applied. I am extremely lost.
Thanks for any help!
I have added this image to show what it looks like so far.

Seems like there really isn't a good none hacky solution. It seems to work quite well with positions and a stack.
Here is the code.
