loading constant
FitGridCellSpec
const loading
A skeleton bar standing in for content that is on its way — a row a data source is still fetching, or the rows below the end while more load.
Painted as a rounded bar rather than left blank, because a blank row reads as "nothing here" while a bar reads as "something coming".
Implementation
static const FitGridCellSpec loading = FitGridCellSpec(
text: '',
style: TextStyle(),
alignment: FitGridAlignment.start,
overflow: FitGridOverflow.clip,
placeholder: true,
semanticLabel: 'Loading',
);
