How did i setup popup AlertDialog? - flutter

Question

How did i setup popup AlertDialog when int is equal or greater than 100?
showDialog(
context: _context,
builder: (BuildContext context) => AlertDialog(
title: Text("$_winner Won"),
)
);
void scoreTeamA() {
setState(() {
outputTeamA += _choiceA;
});
}
// I would like to show outputTeamA on the AlertDialog
Thank you

Answer 1

One way is to create a Widget for the AlertDialog and pass the String/Widget you want to show on that dialog.
class LoadingDialog{
static Future<void> showLoadingDialog(BuildContext context,String text) async {
return showDialog(
context: context,
builder: (BuildContext context){
return SimpleDialog(
children: <Widget>[
Center(
child: Container(
child: Column(
children: <Widget>[
SizedBox(
height:10,
),
Text(text),
]
),
),
),
],
),
}
);
}
}
then you can call on an Event like:
void scoreTeamA(){
outputTeamA += _choiceA;
LoadingDialog.showLoadingDialog(context, outputTeamA);
}
Note: this code might have some errors. i haven't tested this.

This is how I display an AlertDialog
showAlertDialog() {
return showDialog(
context: context,
builder: (context) => AlertDialog(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(30),
side: BorderSide(color: Colors.redAccent, width: 2.0),
),
elevation: 6,
titlePadding: EdgeInsets.all(8.0),
titleTextStyle: TextStyle(
fontSize: 18, color: Colors.red, fontWeight: FontWeight.bold),
title: Text(
'This is the alert title',
textAlign: TextAlign.center,
),
contentPadding: EdgeInsets.all(8.0),
contentTextStyle: TextStyle(fontSize: 14, color: Colors.black),
content: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('Content...')
//content goes here
],
),
actions: <Widget>[
FlatButton(
onPressed: () => Navigator.of(context).pop(), child: Text('Okay'))
],
),
);
}
And then you would do your if check to check
if( outputTeamA >= 100){
showAlertDialog();
}
Of course you could use outputTeamA in AlertDialog
