Resizable

A box which children can be resized along either the horizontal or vertical axis.

class TimeOfDay extends StatelessWidget {
  @override
  Widget build(BuildContext context) => DecoratedBox(
        decoration: BoxDecoration(
          border: Border.all(color: context.theme.colorScheme.border),
          borderRadius: BorderRadius.circular(8),
        ),
        child: FResizable(
          axis: Axis.vertical,
          crossAxisExtent: 300,
          children: [
            FResizableRegion(
              initialExtent: 250,
              minExtent: 100,
              builder: (_, data, __) => Label(data: data, icon: FAssets.icons.sunrise, label: 'Morning'),
            ),
            FResizableRegion(
              initialExtent: 100,
              minExtent: 100,
              builder: (_, data, __) => Label(data: data, icon: FAssets.icons.sun, label: 'Afternoon'),
            ),
            FResizableRegion(
              initialExtent: 250,
              minExtent: 100,
              builder: (_, data, __) => Label(data: data, icon: FAssets.icons.sunset, label: 'Evening'),
            ),
          ],
        ),
      );
}
 
class Label extends StatelessWidget {
  static final DateFormat format = DateFormat.jm(); // Requires package:intl
 
  final FResizableRegionData data;
  final SvgAsset icon;
  final String label;
 
  const Label({required this.data, required this.icon, required this.label, super.key});
 
  @override
  Widget build(BuildContext context) {
    final FThemeData(:colorScheme, :typography) = context.theme;
    final start = DateTime.fromMillisecondsSinceEpoch(
      (data.offsetPercentage.min * Duration.millisecondsPerDay).round(),
      isUtc: true,
    );
 
    final end = DateTime.fromMillisecondsSinceEpoch(
      (data.offsetPercentage.max * Duration.millisecondsPerDay).round(),
      isUtc: true,
    );
 
    return Align(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          Row(
            mainAxisSize: MainAxisSize.min,
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              icon(height: 15, colorFilter: ColorFilter.mode(colorScheme.foreground, BlendMode.srcIn)),
              const SizedBox(width: 3),
              Text(label, style: typography.sm.copyWith(color: colorScheme.foreground)),
            ],
          ),
          const SizedBox(height: 5),
          Text(
            '${format.format(start)} - ${format.format(end)}',
            style: typography.sm.copyWith(color: colorScheme.foreground),
          ),
        ],
      ),
    );
  }
}

Usage

`FResizable(...)`

FResizable(
  controller: FResizableController.cascade(
    onResizeUpdate: (regions) => print(regions),
    onResizeEnd: (regions) => print(regions),
  ),
  axis: Axis.vertical,
  divider: FResizableDivider.dividerWithThumb,
  crossAxisExtent: 400,
  children: [
    FResizableRegion(
      initialSize: 200,
      minSize: 100,
      builder: (context, data, child) => child!,
      child: const Placeholder(),
    ),
  ],
);

Examples

Without Cascading

  @override
  Widget build(BuildContext context) => DecoratedBox(
        decoration: BoxDecoration(

          borderRadius: BorderRadius.circular(8),
        ),
        child: FResizable(
          axis: Axis.vertical,
          controller: FResizableController(),
          crossAxisExtent: 300,
