How to change the background color of the bars in a barchart using react-native-chart-kit

I am using react-native-chart-kit and I am trying to have a cbar chart with any color filling up the bars, as of now it is gray but I am trying to change it but i have tried adding color: {} within the datasets part, as well as svg. But to no success. Any suggestions will be greatly appreciated.

render() {
        return (
            <View>
                <BarChart
                    data={{
                        labels: [
                            '1',
                            '2',
                            '3',
                            '4',
                            '5',
                            '6',
                            '7'
                        ],
                        datasets: [
                            {
                                data: this.props.data,
                            },
                        ],
                    }}
                    svg={{ fill: 'green' }}
                    width={Dimensions.get('window').width - 16}
                    height={220}

                    chartConfig={{
                        backgroundColor: '#fff',
                        backgroundGradientFrom: '#fff',
                        backgroundGradientTo: '#fff',
                        decimalPlaces: 2,
                        color: (opacity = 1) => `rgba(0, 0, 0, ${opacity})`,
                        style: {
                            borderRadius: 16,
                        },
                        propsForDots: {
                            r: "0",
                            strokeWidth: "2",
                            stroke: "#fff"
                        },
                        propsForBackgroundLines: {
                            strokeWidth: 0
                        },
                    }}
                    style={{
                        marginVertical: 8,
                        borderRadius: 16,
                    }}
                />
            </View>
        );
    }

You can set fillShadowGradient and fillShadowGradientOpacity in your chartConfig.
