Allow customization of CalendarList loading placeholder

[jeferson-sb]

Description

Whenever you have CalendarList loading there is a quick flash of a <Text> showing for each of the months (calendars) being rendered. But looking into the props there were no options to either replace the text or change its string.

I found out to be this guy:

https://github.com/wix/react-native-calendars/blob/da9b1bd702e1221002d6e30aaf888e350b627b6a/src/calendar-list/item.tsx#L84-L88

And the styles:

Expected Behavior

I expect to be able to at least change the style of the placeholder text.

Observed Behavior

See example below:

Pay attention to the 2024-05-01 text showing in the place of the calendar

https://github.com/wix/react-native-calendars/assets/30840709/f1139327-3a0a-4221-8f14-60ddc892b5c7

Code:

import React from 'react';
import {CalendarList} from 'react-native-calendars';

export const MyCalendar = () => {
  return (
    <CalendarList
      showScrollIndicator
      pastScrollRange={5}
      futureScrollRange={5}
    />
  );
};

I would also like this to be implemented. I can submit a PR

[jeferson-sb]

I was able to circumvent this for now changing the theme with:

const calendarTheme = {
  'stylesheet.calendar-list.main': {
    placeholder: {
       // wrapper styles
    },
    placeholderText: {
      // text styles
    },
  },
};

export default calendarTheme;

Consegui contornar isso por enquanto mudando o tema com:

You change the text as well or just the styles? @jeferson-sb

[jeferson-sb]

@vagnereix Only styles

yes, i hate this, how this lib cannot have something as basic as a loader component customizable? terrible

@lestercorderomurillo you are always welcome to submit a PR for this or fork the library and implement it yourself.

Kindly remember that you are not paying for this library and people developing it are not getting any money from it.

I would recommend you being more respectful towards who helps building open source software. As, without them, you wouldn't even have a place to call another's person work terrible 😄

Community input is always welcome, but being kind is a must
