StreamChannelGridView
A Widget For Displaying A List Of Channels
Find the pub.dev documentation here
Background
The StreamChannelGridView
widget allows displaying a list of channels to a user in a GridView
.
Make sure to check the StreamChannelListView documentation to know how to show results in a ListView
.
Basic Example
Here is a basic example of the StreamChannelGridView
widget. It consists of the main widget itself, a StreamChannelListController
to control the list of channels and a callback to handle the tap of a channel.
This example by default displays the channels that a user is a part of. Now let’s look at customizing the widget.
