In this step, I implement the home screen to match the design. The design is as follows:

The home screen design is implented in three steps:

• Implementing the custom header

• Implementing the summary div, spendings div, and earnings div

• Implementing the floating button

Implementing the Custom Header

The default header only displays the page title. However, the design has a home icon instead of the page title. Therefore, the custom header is to include a home icon. I also centered it, as there was no option to align it on the far-right. To add a custom header, I used the headerTitle option and passed the customHeader component to it. This is in the home page which is the navigation drawer wrapper page (it contains all the page routes for the drawer). In the customHeader component, I added the icon.

Home.js - homePage route

<Drawer.Screen
        name="HomePage"
        component={HomePage}
        options={{
          drawerIcon: ({ color }) => (
            <FontAwesome name="home" size={20} color={color} />
          ),
          headerTitle: (props) => <CustomHeader {...props}/>,
          headerTitleAlign:"center"
        }}
      />

customHeader

function CustomHeader({name}) {
  return (
    <View>      
        <AntDesign name="home" size={24} color="black" />      
    </View>
  );
}

Now there's a home icon on top of the homepage instead of a text title.

Homepage Divs

The home page has five divs/containers. The summary container, the chart container, the spendings container, and the earnings container. I included a universal 15px margin for all containers. I bundled these divs in a scrollView.

Summary Container

• Styled the texts to match the font-family and the font-size

Chart Container

• Used a chart from react-native-chart-kit. https://www.npmjs.com/package/react-native-chart-kit

Spendings Container and Earnings Container

• These two share the same layout.

• For the heading row I used flexDirection and justifyContent to display both texts in a row and on both ends of the screen.

• For the content rows, I created a component displayRow and styled the icon image and the texts as expected.

Floating Button

For the floating button, I needed a green button displayed at the bottom of the screen. For it to appear on top of the other content, I placed it outside the scrollview and also gave it a flex value of 0 and a marginBottom. I then added a TouchableOpacity, which is the equivalent of a button wrapper, and an icon (the plus button) inside the touchable opacity. I styled both appropriately giving them a background colour, border radius (for it to be round) and text-color.

The final code on the homepage and the displayRow component is as follows:

HomePage.js

return (
    <View style={styles.container}>
      <ScrollView>
        {/* summary container */}
        <View style={[styles.homeDiv, styles.homeSummary]}>
          <Text style={styles.summHeading}>Kes 2000</Text>
          <Text style={styles.summText}>Total Spent This Week </Text>
        </View>
        {/* end of summary container */}
        {/* chart container */}
        <View style={[styles.homeDiv]}>
          <BarChart
            data={{
              labels: ["January", "February", "March", "April", "May", "June"],
              datasets: [
                {
                  data: [20, 45, 28, 80, 99, 43],
                },
              ],
            }}
            width={Dimensions.get("window").width - 30}
            height={220}
            yAxisLabel={"Rs"}
            chartConfig={{
              backgroundColor: "#1cc910",
              backgroundGradientFrom: "#eff3ff",
              backgroundGradientTo: "#efefef",
              decimalPlaces: 2,
              color: (opacity = 1) => `rgba(0, 0, 0, ${opacity})`,
              style: {
                borderRadius: 16,
              },
            }}
            style={{
              marginVertical: 8,
              borderRadius: 16,
            }}
          />
        </View>
        {/* end of chart container */}
        {/* spending container */}
        <View style={[styles.homeDiv, styles.homeSpending]}>
          {/* header row */}
          <View style={styles.row}>
            <Text style={styles.rowHeading}>Recent Spending</Text>
            <TouchableOpacity>
              <Text style={styles.summText}>View All</Text>
            </TouchableOpacity>
          </View>
          {/* contents row */}
          <View>
            <DisplayRow />
            <DisplayRow />
            <DisplayRow />
          </View>
        </View>
        {/* end of spending container */}
        {/* earning container */}
        <View style={[styles.homeDiv, styles.homeSpending]}>
          {/* header row */}
          <View style={styles.row}>
            <Text style={styles.rowHeading}>Recent Income</Text>
            <TouchableOpacity>
              <Text style={styles.summText}>View All</Text>
            </TouchableOpacity>
          </View>
          {/* contents row */}
          <View>
            <DisplayRow />
            <DisplayRow />
            <DisplayRow />
          </View>
        </View>
        {/* end of earning container      */}
      </ScrollView>
      {/* floating button */}
      <View style={[styles.footer]}>
        <TouchableOpacity style={styles.floatingBtn}>
          <AntDesign name="plus" size={24} color="white" />
        </TouchableOpacity>

  );

Styling:

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: "flex-start",
    alignItems: "flex-start",
    alignContent: "center",
    backgroundColor: "#fff",
  },  
  row: {
    flexDirection: "row",
    justifyContent: "center",
    width: Dimensions.get("screen").width,
  },
  homeDiv: {
    margin: 15,
  },
  summHeading: {
    fontSize: 24,
    fontFamily: "PoppinsBold",
  },
  summText: {
    fontSize: 14,
    fontFamily: "Poppins",
  },
  homeSpending: {
    borderColor: "#12B886",
    borderWidth: 1,
    width: Dimensions.get("screen").width - 30,
    padding: 10,
    borderRadius: 8,
  },
  homeEarnings: {
    borderColor: "#12B886",
    borderWidth: 1,
    width: Dimensions.get("screen").width - 30,
    padding: 10,
    borderRadius: 8,

    height: 10,
    alignContent: "flex-end",
    alignItems: "flex-end",
    marginHorizontal: 10,
    width: Dimensions.get("screen").width - 30,
  },
  floatingBtn: {
    backgroundColor: "#12B886",
    padding: 10,
    borderRadius: 100,
    width: 60,
    height: 60,
    justifyContent: "center",
    alignContent: "center",
    alignItems: "center",
  },
});

DisplayRow.js

import { StyleSheet, Text, View, Image } from "react-native";
import { AntDesign } from "@expo/vector-icons";

export default function DisplayRow() {
  return (
    <View style={styles.row}>
      <View style={styles.col}>
        <Image
          source={{
            uri: "https://img.icons8.com/fluency/512/home-page.png",
          }}
          style={{ width: 40, height: 40, marginRight:10 }}
        />
        <View>
          <Text style={styles.heading}>Rent</Text>
          <Text style={styles.text}>Yesterday</Text>
        </View>
      </View>
      <View>
        <Text style={styles.heading}>-Kes 10,000</Text>
      </View>
    </View>
  );
}

const styles = StyleSheet.create({
  row: {
    flexDirection: "row",
    justifyContent: "space-between",
    alignContent: "center",
    alignItems: "center",
    marginVertical:10
  },
  col: {
    flexDirection: "row",
    alignContent: "center",
    alignItems: "center",
  },
  heading:{
    fontFamily:"PoppinsBold",
    fontSize:15,
  },
  text:{
    fontFamily:"Poppins"
  }
});

Output:

Next is to implement the floating button animation once it is clicked.
