              bottom: 0,
              zIndex: 1,
              alignSelf: 'center',
            }}

      </View>
      <View
        style={{
          backgroundColor: '#0096FF',
          justifyContent: 'center',
          paddingHorizontal: '5%',
          height:200,
          marginBottom:75
        }}>
        <Text style={{color: '#e2ffff', fontSize: 14, fontFamily: 'Poppins'}}>
          Sales-Today
        </Text>
        <View style={{flexDirection: 'row'}}>
          <Text
            style={{

            ₹ 2,945769.34
          </Text>
        </View>
