How to Set the loading value for the Circular progresss indicator like progress percentage in flutter for 60 days-Math formula?I need this stuff for my flutter project,Sorry if i am asking something silly:-) Note : I'm new to this amazing flutter development.
You can set "completed" rate of a progress indicator like this:
CircularProgressIndicator(value: 0.5)
The above will result in a 50% indicator. All you have to do is use a member as value in a StatefulWidget
and use setState
to update it according to the desired percentage.
Also you can use it to indicate the progress when loading an image:
Image.network(
'<url>',
height: 50,
loadingBuilder: (BuildContext context, Widget child,
ImageChunkEvent? loadingProgress) {
if (loadingProgress == null) {
return child;
}
return Center(
child: CircularProgressIndicator(
value: loadingProgress.expectedTotalBytes != null
? loadingProgress.cumulativeBytesLoaded /
loadingProgress.expectedTotalBytes!
: null,
),
);
},
)
