A widget displaying children in a line with an overflow indicator at the end if there is not enough space.

Pub

Features #

  • Renders children horizontally or vertically.
  • Has an overflow indicator builder so that you can display a widget showing the number of elements not rendered.
  • Can either constrain the children to the size of the first child or let them have the size they want.

Overview

Getting started #

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  overflow_view:

In your library add the following import:

import 'package:overflow_view/overflow_view.dart';

Usage #

OverflowView(
  // Either layout the children horizontally (the default)
  // or vertically.
  direction: Axis.horizontal,
  // The amount of space between children.
  spacing: 4,
  // The widgets to display until there is not enough space.
  children: <Widget>[
    for (int i = 0; i < _counter; i++)
      AvatarWidget(
        text: avatars[i].initials,
        color: avatars[i].color,
      )
  ],
  // The overview indicator showed if there is not enough space for
  // all chidren.
  builder: (context, remaining) {
    // You can return any widget here.
    // You can either show a +n widget or a more complex widget
    // which can show a thumbnail of not rendered widgets.
    return AvatarWidget(
      text: '+$remaining',
      color: Colors.red,
    );
  },
)

Constructors #

There are two constuctors depending on what you want to do.

The OverflowView constructor will constrain all children to have the same size as the first one. This can be used for an avatar list for example.

The OverflowView.flexible constructor will let all children to determine their own size. This is less performant than the default one, but it's more flexible. This can be used for a menu bar for example.
