Bug on Toast with keyboard open

[fqr1]

I have a Button that triggers the Toast, and a TextInput that triggers the Toast too,
If I press one and wait until is closed, to trigger the second Toast, it works normally (for example, press the button, wait until the Toast is close, and write in the TextInput)

But the problem goes when the second Toast is shown, but the first Toast is not closed yet. The message is shown twice in the device

Usage example:

Code:

import React, {Component} from 'react';
import {
    View, StyleSheet, Text, Button, TextInput
} from 'react-native';

import Toast from 'react-native-toast-native';

class ToastComponent extends Component {

    onChange(){
        Toast.show(
            'onChange toast.',
            Toast.LONG,
            Toast.BOTTOM
        );
    }

    buttonPressed(){
        Toast.show(
            'Button toast.',
            Toast.LONG,
            Toast.BOTTOM
        );
    }

    render() {
        return (
            <View style={styles.main}>
                <Text>react-native-toast-native</Text>
                <Button title="Button" onPress={this.buttonPressed.bind(this)}/>
                <TextInput onChange={this.onChange.bind(this)} style={styles.input}/>
            </View>
        );
    }
}

const styles = new StyleSheet.create({
    main: {},
    input: {
        backgroundColor: 'lightblue'
    }
});

export default ToastComponent;
