Did you config fullscreen plugin in graph options? Could you provide the codes.

[Yuhemei]

const fullScreenPlugin: Fullscreen = graph.getPluginInstance(
    'plugin-fullscreen-0',
  );
  fullScreenPlugin.request();

生效了。
原因是 graph.context.plugin.extensionMap是plugin-fullscreen-0不是fullscreen
但是用起来很别扭，期待团队早日更新

Yes,this is my code

plugins: [
      'minimap',
      'fullscreen',
      ...
]

my dependencies version is "@antv/g6": "^5.0.16",
you can try it.

[Aarebecca]

The main reason is that once you do not assign a key for the plugin, G6 will generate one automatically. Hence, if you want to get the plugin instance, you'd better configure as follows:

Graph options:

plugins: [
  'minimap',
  {
    type: 'fullscreen',
    key: 'fullscreen'
  }
]

Use:

import type { Fullscreen } from '@antv/g6';

const fullscreen = graph.getPluginInstance<Fullscreen>('fullscreen');

@Yuhemei Hi, we enhanced the getPluginInstance API in #6215, you can use it in the next version, but its return is ambiguous, so it will print a warning in console.
