Hi @pierinaaguirre, I can't figure out exacly what happen. But you should Be able to use the calendar together with anything you want In your Page.

You could use de Column Widget to group any Widgets you want with our Calendar.

Here is an example with the stucture you told above.

Column(
  children: [
    Container(
      child: Text('My Container with a Text'),
    ),
    TextButton(
      child: Text('My Button'),
      onPressed: () {},
    ),
    ScrollableCleanCalendar(
      calendarController: calendarController,
      layout: Layout.BEAUTY,
      calendarCrossAxisSpacing: 0,
    ),
  ],
),

Tell me if this help. And thanks for your feedback

Hello, I have copied the lines of code that you wrote, but I get the same error as always, it is the following:
======== Exception caught by rendering library =====================================================
The following assertion was thrown during performLayout():
'package:flutter/src/rendering/object.dart': Failed assertion: line 1814 pos 12: '!_debugDoingThisLayout': is not true.

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:

Hey @pierinaaguirre I test some things here, and I think I found the problem.

Put our calendar Widget inside a Expanded() Widget. Like This:

Expanded(
  child: ScrollableCleanCalendar(
    calendarController: calendarController,
    layout: Layout.BEAUTY,
    calendarCrossAxisSpacing: 0,
  ),
),

See the image from my test. Cya.
