iOS: Not showing Done and Cancel Button on first render, scroll the spin crash the app

[cengit]

React Native version :0.63.3

• when first enter the page and trigger the month-year-picker, Not showing Done and Cancel Button. at this time scroll the spin would some times make the app crash.
• navigate to other page and navigate back, re-trigger the month-year-picker, it works fine.

as it would crash the app, I guess is there some code issue in this situation?

attached the screen and video. thanks

this is my code:

render() {
    const { value, minimumDate, maximumDate, locale } = this.state;
    return (
      <MonthPicker
        onChange={this.onValueChange}
        value={value}
        minimumDate={minimumDate}
        maximumDate={maximumDate}
        mode="full"
        autoTheme={false}
        locale={locale}
      />
    );
  }

I found the root cause: when the locale=null, it would reproduce above issue

use below code would fix the problem.

<MonthPicker
        onChange={this.onValueChange}
        value={value}
        minimumDate={minimumDate}
        maximumDate={maximumDate}
        mode="full"
        autoTheme={false}
        locale={locale || 'en'}
      />

closing the issue
