tried to fix this issue here, but I don't understand what could be causing it...
I was using the Calendar component in my project with no issues. However, I decided it would be more convenient replacing it by the DatePicker, which apparently uses pretty much the same. Here is the code I have so far (relevant part):
import React from 'react';
import {
Alert,
ScrollView,
StyleSheet,
View,
InteractionManager,
Image,
TextInput,
TouchableOpacity,
BackHandler
} from 'react-native';
import {
Card,
CardHeader,
Layout,
Text,
Calendar,
DatePicker,
Spinner,
} from '@ui-kitten/components';
import { TaskCard } from './components/task-card';
import { validate } from 'validate.js';
import { Auth, Storage, API, graphqlOperation, scTracker } from '../modules/commons';
import Styles from '../modules/styles';
import constraints from './fields/constraints';
import Ionicons from 'react-native-vector-icons/Ionicons';
import { CustomCalendar } from './components/custom-calendar';
class TasksScreen extends React.Component {
static navigationOptions = {
title: "Atividades",
};
state = {
cDate: null,
showCalendar: false,
};
constructor(props) {
super(props);
};
componentDidMount() {
try {
let lcDate = new Date();
this.setState({
cDate: lcDate,
});
} catch (e) {
console.log(e);
};
};
render() {
return(
. . . . .
<Layout level="2" style={{width:"100%"}}>
<DatePicker date={this.state.cDate}
onSelect={(date)=>{this.setState({cDate: date})}}
/>
</Layout>
<ScrollView contentContainerStyle={Styles.vScrollViewContent}>
<TaskCard
. . . . . .
But for some reason, with exactly the same parameters, it started to trigger an error pointing exactly on the line of the Layout wrapping the date picker (alog with all other Layout objects):

Thanks in advance folks!!
There is no DatePicker component in this library. However, there is Datepicker
