List of helpers

Name description status
Mr Rwema An helper do describe another widget of your page. This creates an overlay above your page

Anchored helper

This widgets is highly inspired by google onboardings. This shows a circle around any widgets you want and add an overlay were you can add a message.

First embbed you page or your app with a HelperOrchestrator widget.

    child: Scaffold(
        appBar: AppBar(
            title: Text(widget.title),
        body: ...

You now have to get a key text1 for the widget you want to reference using

    key: HelperOrchestrator.of(context).generateKey('text1'),


You can now show an anchored helper using

final helper = AnchoredHelper(
    anchorKeyId: 'text1',
    title: const Text('Title lorem pitume'),
    description: const Text('Lorem ipsum lorem ipsum lorem ipsum lorem ipsum lorem ipsum'),,
    bgColor: Colors.blue,
    leftBtnText: const Text('cancel'),
    rightBtnText: const Text('Ok, understood'),
    onError: () => print("widget not found"),
    positivBtnStyle: helperOutlineBtnStyle,
    negativeBtnStyle: helperOutlineBtnStyle,
    onLeftBtnTap: () => HelperOrchestrator.of(context).hideHelper(),
    onRightTap: () => HelperOrchestrator.of(context).hideHelper(),
    onTapAnchor: () => HelperOrchestrator.of(context).hideHelper(),

// this will show an overlayed anchored widget using the key text1
HelperOrchestrator.of(context).showAnchoredHelper('text1', helper);
