topGap property

  1. @override
double get topGap

The gap between the top of the screen and the top of the sheet as a ratio of the screen height.

This value should be between 0.0 and 0.9, where 0.0 means no gap (sheet extends to the top of the screen) and 0.9 means the sheet covers only the bottom 10% of the screen. A value of 0.08 represents 8% of the screen height.

If not provided, defaults to a value of 0.08.

Implementation

@override
double get topGap => _topGap ?? _kTopGapRatio;
