Thanks
Here is the code without body of the widget:
Column(
children: [
Material(
elevation: 0,
child: Image.asset(
i.first,
fit: BoxFit.fitWidth,
),
),
SizedBox(
width: 130,
child: FittedBox(
fit: BoxFit.fitWidth,
child: Padding(
padding: const EdgeInsets.all(30.0),
child: Text(
i.last
),
),
),
),
],
Need to add space between appbar and image.
How can i achieve additional space between image and appbar widgets?
You can use Padding Widget:
body: Padding(
padding: const EdgeInsets.all(8.0),
child: GridView.count(
crossAxisCount: 2,
children: [
...myImageAndCaption.map(
(i) => Column(
mainAxisSize: MainAxisSize.min,
children: [
Material(
elevation: 0,
child: Image.asset(
i.first,
fit: BoxFit.fitWidth,
height: 150,
width: 150,
),
),
SizedBox(
width: 130,
child: FittedBox(
fit: BoxFit.fitWidth,
child: Padding(
padding: const EdgeInsets.all(30.0),
child: Text(
i.last,
style: const TextStyle(
fontSize: 22,
letterSpacing: 1.0,
fontWeight: FontWeight.w600,
color: Colors.black,
),
),
),
),
),
],
),
),
],
),
),
I'm fairly new to software dev using Flutter/Dart and I'm currently working on a widget that uses listview to display the information entered by a user. This information is currently stored in a List and for some reason, each time I add new info to the list, only the info at the first index is printed. I'm not actually getting any error message so it's pretty hard to trace it. I've tried debugging it using print statements but it's really not helping me.
The second problem is that when the user chooses a picture from their gallery, it isn't immediately displayed.
How can I fix these things?

The reason the listView.builder is not functioning correctly is that you have declared the variables in the CardRow Widget and are using those static values instead of the arguments that you have passed. You are passing the arguments, you just aren't using them.
The only change I did here:
final EmergencyContact emergencyContact;
//static File emergencyContactPic = _EmergencyContactsState._contactPic;
// static String emergencyName = _EmergencyContactsState.emergencyName;
// static String emergencyNumber = _EmergencyContactsState.phoneNumber;
// static String emergencyEmail = _EmergencyContactsState.emailAddress;
CardRow(this.emergencyContact);
Here is where I extracted your widgets as methods(just the ones passed in the argument), the reason I did this was that this can't be accessed in the initializers that you had done. I would recommend you to start using final more, and extracting your Widgets into their own Stateful/Stateless Widgets, or as methods, as I have done below. It's good practice.

children: <Widget>[
contactCard,
contactCardContent(),
contactThumbnail(),
deleteContact,

Container contactThumbnail() {
return Container(

Second Problem
For your second problem, the reason you don't see the image being displayed immediately is that the showDialog is not being rebuilt. To explicate more on this, the setState that is being used in the showAlertDialog function belongs to the parent Widget, so, that means that it is only going to be rebuilding what is outside of that particular function. The showAlertDialog function only gets rebuilt when you first click on it. In order to fix this, we will either have to put the showDialog in a Stateful widget or use a StatefulBuilder (https://api.flutter.dev/flutter/widgets/StatefulBuilder-class.html)
The StatefulBuilder comes with its own setState construction, meaning it can now get rebuilt when using setState, resulting in displaying the image immediately. BUT now we have another issue, I see you have the boolean buttonPressed in there, that whole setState(boolean) belongs to the parent widget, not the StatefulBuilder setState, so now this means that the list will not be displayed after "add contacts" is pressed until it gets rebuilt. We need the setState from the parent, not from the StatefulBuilder. There are many ways to fix this, but I personally think using a callback is one of the best. First, you will need to create a function, like rebuildWidget and simply change the state right there. Secondly, pass that function down to showAlertDialog as an argument. Thirdly, go ahead and create a final Function and then assign it. Last, simply call it on the onPressed.
void rebuildWidget() {
setState(() {
buttonPressed = true;
});
}
showAlertDialog(
context,
rebuildWidget
);
showAlertDialog(BuildContext context, myState) {
final Function() updateParent = myState;
showDialog(
context: context,
builder: (context) {
String contentText = "Content of Dialog";
File myPic;
return StatefulBuilder(
builder: (context, setState) {

I am calling this dialog while getting data from server. This dialog box is having white spaces around it. I can I remove this white space around my dialog box. Here is my code.
var bodyProgress = new Container(
decoration: new BoxDecoration(
color: Colors.blue[200],
borderRadius: new BorderRadius.circular(10.0)
),
width: 300.0,
height: 200.0,
//color: Colors.blue,
alignment: AlignmentDirectional.center,
child: new Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Center(
child: new SizedBox(
height: 50.0,
width: 50.0,
child: new CircularProgressIndicator(
value: null,
strokeWidth: 7.0,
),
),
),
new Container(
margin: const EdgeInsets.only(top: 25.0),
child: new Center(
child: new Text(
"Signing up...",
style: new TextStyle(
color: Colors.white
),
),
),
),
],
),
);
Here I am calling this dialog. I've tried with both AlertDialog() and SimpleDialog() having same issue with both.
showDialog(context: context, child: new AlertDialog(
content: bodyProgress,
));
Inside AlertDialog set contentPadding 0
contentPadding: EdgeInsets.zero,
make title to have Container, and add
width: MediaQuery.of(context).size.width,
Then give 0 (or what value you want to have for horizontal patting) to insetPadding like this:
insetPadding: EdgeInsets.symmetric(horizontal: 0),
Below is my example show dialog code, contains alertDialog with horizontal padding = 15 :
Future<void> _showLogoutDialog(BuildContext context) async {
return showDialog<void>(
context: context,
barrierDismissible: true,
builder: (BuildContext context) {
return AlertDialog(
titlePadding: EdgeInsets.only(top: 12, left: 24, right: 12),
contentPadding: EdgeInsets.only(top: 12, left: 24, bottom: 20),
insetPadding: EdgeInsets.symmetric(horizontal: 15),
titleTextStyle: TextStyle(
color: ColorStyles.primary_blue500,
fontFamily: 'Muli',
fontWeight: FontWeight.w500,
fontStyle: FontStyle.normal,
fontSize: 16.0,
),
contentTextStyle: TextStyle(
color: ColorStyles.grey2,
fontFamily: 'Muli',
fontWeight: FontWeight.w400,
fontStyle: FontStyle.normal,
fontSize: 14.0,
),
title: Container(
width: screenUsableHeight(context),
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text('Log out'),
IconButton(
icon: Icon(
Icons.close,
color: ColorStyles.grey2,
size: 28,
),
onPressed: () => Navigator.of(context).pop(),
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
tooltip: "close",
)
],
),
),
//EN: Logging out
content: SingleChildScrollView(
child: ListBody(
children: <Widget>[
Text('Do you want to leave?'),
],
),
),
actions: <Widget>[
FlatButton(
child: Text(
'Yes',
style: TextStyle(
color: ColorStyles.primary_blue500,
fontFamily: 'Muli',
fontWeight: FontWeight.w500,
fontStyle: FontStyle.normal,
fontSize: 16.0,
),
), //EN: Yes
onPressed: () {
_logOut(context);
},
),
FlatButton(
child: Text(
'No',
style: TextStyle(
color: ColorStyles.grey2,
fontFamily: 'Muli',
fontWeight: FontWeight.w500,
fontStyle: FontStyle.normal,
fontSize: 16.0,
),
), //EN: No
onPressed: () {
Navigator.of(context).pop();
},
),
],
);
},
);
}
This looks like:
display of alert dialog
titlePadding: EdgeInsets.zero,
contentPadding: EdgeInsets.zero,
Don't use AlertDialog at all. Just send bodyProgress to showDialog
showDialog(context: context, builder: (_) => bodyProgress,);
add the file to your project https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/material/dialog.dart, use the CustomAlertDialog and set the contentPadding to 0.0 by using EdgeInsets.all(0.0), finally adjust the border raidius to that of your bodyprogress
use like this ->
using get: ------------->
Get.generalDialog(
pageBuilder: (BuildContext buildContext, Animation animation,
Animation secondaryAnimation) =>
AlertDialog(
contentPadding: EdgeInsets.zero,
// this padding user for outside of alert padding
insetPadding: EdgeInsets.symmetric(horizontal: 10),
content: Container(
height: Get.height - 300, // Change as per your requirement
width: Get.width, // Change as per your requirement
child: <Your Widget>
),
),
));
using alert dialog:------>
CustomAlertDialog(
content: new Container(
width: 260.0,
height: 230.0,
decoration: new BoxDecoration(
shape: BoxShape.rectangle,
color: const Color(0xFFFFFF),
borderRadius:
new BorderRadius.all(new Radius.circular(32.0)),
),
child: <Your widget>
),
);
});
