Description

While using a third party package,
https://www.npmjs.com/package/react-native-numeric-input
I am trying to make a text input which can be incremented, which can accept decimal inputs as well.
This works fine while running the app in iOS, but in Android, the decimal is not accepted, or in other words, is removed as soon as it is entered.

Reproducible Demo

Unfortunately, the app and code is confidential, but the part of the package mentioned which seems to be responsible for this behaviour is mentioned below. Although I think this might be something related to react-native and not the package.

onChange = (value) => {
        let currValue = typeof this.props.value === 'number' ? this.props.value : this.state.value
        let realMatch = value && value.match(/\d+(\.(\d+)?)?/) && value.match(/\d+(\.(\d+)?)?/)[0] === value.match(/\d+(\.(\d+)?)?/).input,
            intMatch = value && value.match(/\d+/) && value.match(/\d+/)[0] === value.match(/\d+/).input,
            legal = value === '' || (((this.props.valueType === 'real' && realMatch) || (this.props.valueType !== 'real' && intMatch)) && (this.props.maxValue === null || (parseFloat(value) <= this.props.maxValue)) && (this.props.minValue === null || (parseFloat(value) >= this.props.minValue)))
        if (!legal) {
            if (this.ref) {
                this.ref.blur()
                setTimeout(() => {
                    this.ref.clear()
                    setTimeout(() => {
                        this.props.onChange && this.props.onChange(currValue - 1)
                    this.setState({ value: currValue - 1 }, () => {
                        this.setState({ value: currValue })
                        this.props.onChange && this.props.onChange(currValue)
                    })},10)
                }, 15)
                setTimeout(() => this.ref.focus(), 200)

            }
        } else {
            this.setState({stringValue:value})
            let parsedValue = this.props.valueType === 'real' ? parseFloat(value) : parseInt(value)
            parsedValue = isNaN(parsedValue) ? 0 : parsedValue
                if (parsedValue !== this.props.value)
                    this.props.onChange && this.props.onChange(parsedValue)
                this.setState({ value: parsedValue })
         
        }
    }
