Dynamic icon size in Material-UI - css

I use materiel-UI icon
<ArrowRightAlt/>
I can control the size of the icon by fontSize
<ArrowRightAlt fontSize="large" />
But I want v size to depend on window size (like md,xs,sm)
Can this be done?

Below is one way of doing this using Box. I'm changing color in addition to font-size just to make it easier to tell which breakpoint it is at.
import React from "react";
import ArrowRightAlt from "#material-ui/icons/ArrowRightAlt";
import Box from "#material-ui/core/Box";
export default function App() {
return (
<Box
clone
color={{ xs: "red", sm: "orange", md: "yellow", lg: "green", xl: "blue" }}
fontSize={{ sm: 48, md: 96, lg: 192, xl: 384 }}
>
<ArrowRightAlt />
</Box>
);
}

Position leaflet map in flex column and make it fill whole container

I have something like this:
These are two different breakpoints. When container is stretched by form, map fills its container, but when flex changes direction to row it does not. How do I fix this without giving fixed value for map height?
I am using Chakra UI lib but it does not really matter, pure css solution is also fine.
<Stack mt="2" direction={{ base: 'column', md: 'row' }}>
<Box
flex={{ md: 1, sm: 1, lg: 2 }}
bg="white"
p="2"
shadow="sm"
borderRadius="4"
>
<CreateDeviceMap
zoom={10}
style={{ height: '100%' }}
center={[51.472829664858644, -0.06935119628906251]}
/>
</Box>
<Stack
flex="1"
bg="white"
shadow="sm"
p="4"
spacing="2"
borderRadius="4"
>
... form
</Stack>
</Stack>
UPDATE:
If I put height:100vh to container map shows and it is fine on small breakpoint but it destroys bigger breakpoints, they become streched. So I just need to find sweet spot between them.

ReactNative Layout Process & how flex impacts it?

I am trying to understand why the below layouts work differently.
Can someone explain how the internal layout process happen, in terms of rules? And why below examples behave differently. Except just saying that this is how it is.
Example1:
return (
<View style = {{borderWidth : 1, borderColor : 'red'}}>
<View style = {{borderWidth : 1, borderColor : 'black'}}>
<Text>TestText</Text>
</View>
</View>
)
This renders the red box around the black box around the Text. Which means that View resizes based on its content. inner view resizes to consider the text, outer view considers inner view(which already has considered inner text to determine its dimensions), hence everything is as expected.
Example2:
return (
<View style = {{borderWidth : 1, borderColor : 'red'}}>
<View style = {{flex:1,borderWidth : 1, borderColor : 'black'}}>
<Text>TestText</Text>
</View>
</View>
)
The text now comes outside both the Views. The inner view still rests inside the outer view though.
Now i tried a little different variation:
Example3:
return <View style = {{borderWidth:1, borderColor:'red', height:10}}>
<View style = {{flex:1, borderWidth:1, borderColor:'black'}}>
<Text>HelloWorld</Text>
</View>
</View>
This one renders a little better, i.e the text atleast seems to start inside both the views. But still not as expected.
Questions i have:
1) in case #2 above, Why does the text flow outside both the views? Whereas inner View still stays inside outer?
Can some content ever go beyond the bounds of its parent View? Shouldn't the parent View expand to contain it, as long as we haven't provided specific dimensions to it?
2)In case #3, things behave a little bit as expected..Text is inside the views somewhat, but still overflows..
3)How does this rendering happen in ReactNative internally & how does it determine the effective heights of these views above?
Example with flex
flex: 1, obligates child to follow parent's height, "Black view" will fill all the space available of the "Red view", which is height:60.
<View style={{ borderColor: "red", height: 60 }}>
<View style={{ borderColor: "black", flex: 1 }}>
<Text>HelloWorld</Text>
...
</View>
</View>
Example without flex:1
Here without flex, "Black view" will occupy all space of its children, it won't matter height of the parent ("Red view").
<View style={{ borderColor: "red", height: 60 }}>
<View style={{ borderColor: "black" }}>
<Text>HelloWorld</Text>
...
</View>
</View>
The thing is in simple terms the outline misbehaves in case of 2nd one , i.e :
<View style = {{borderWidth : 1, borderColor : 'red'}}>
<View style = {{flex:1,borderWidth : 1, borderColor : 'black'}}>
<Text>TestText</Text>
</View>
</View>
Is because the parent View component doesnt have a flex property so it doesnt take up whole the space and since you have added flex:1 in the child View it tries to take up as whole space as its alloted , hence black border Dominates and TestText is below it.
But if you provide flex:1 , to parent View you will see the same structure as it was with no flex given at all. Try :
<View style = {{flex:1,borderWidth : 1, borderColor : 'red'}}>
<View style = {{flex:1,borderWidth : 1, borderColor : 'black'}}>
<Text>TestText</Text>
</View>
</View>
Hope it helps . feel free for doubts

How to set breakpoints in Material ui grid to make it responsive

I am using Material ui Grid to arrange my ui elements. Below is my code
<Grid container spacing={3}>
<Grid container item xs={12} sm={12} md={12} style={{ marginTop: '-1.5%', marginRight: '1%' }}>
<Grid item xs={7} sm={7} md={7}>
<label className={classes.title}> Title </label>
</Grid>
<Grid item xs={5} sm={5} md={5}>
<label style = {{marginLeft: '25%'}}> Lable 1 </label>
<label> Lable 2 </label>
</Grid>
</Grid>
Now, as per the above code, i want to make design responsive based on screen sizes and add breakpoints, how can i achieve it? Also, is there any way to handle the browser resolution/zoom, my design goes to horizontal scroll with bigger zoom.
To make this work import
import {createMuiTheme,ThemeProvider} from "#material-ui/core/styles"
As stated above you use the following code to set your breakpoints. You are not limited to the pre defined names you can use any name you want. The values are the min-width for the breaking point. So in this case XS stops at 449px.
const theme = createMuiTheme({
breakpoints: {
values: {
xs: 0,
sm: 450,
md: 600,
lg: 900,
xl: 1200,
tablet:1024
}
}
});
You then have to use a theme provider to implement it.
<ThemeProvider theme={theme}>
<Grid container><Grid item xs={12}>Some stuff</Grid></Grid>
</ThemeProvider>
The Grid is already responsive.
Setting md to be below 12 to set breakpoints for lager screens.
For even larger screens use lg and xl.
It will respect browser resolution/zoom and will automatically put components in a new line, if the screen size is below the given break point.
To add custom break points, you can add these options to create mui theme:
const theme = createMuiTheme({
breakpoints: {
values: {
xs: 0,
sm: 450,
md: 600,
lg: 900,
xl: 1200
}
}
});

How can I disable double border on every TouchableOpacity?

I'm making an React Native App in which i have 2 buttons/ TouchableOpacity's. When styling these buttons, they both get double border even when explicitly stating 'solid' borderstyle in the respective stylesheets. ( On the attached screenshot the middle button is all white, but when I make the border a different color it is a double one as well ). No where in the whole file have I defined a double borderstyle.
bottom left button stylesheet:
roomsbutton: {
alignItems: 'center',
backgroundColor: '#009DDC',
padding: 5,
borderRadius: 2,
borderWidth: 1,
borderStyle: "solid",
borderColor: 'white',
color: 'white',
}
and its parent view:
<View style={styles.bottom}>
<TouchableOpacity
style={styles.roomsbutton}
onPress={() => Alert.alert('more rooms')}
>
<Text style={styles.roomsbutton} >FIND MORE FREE ROOMS</Text>
</TouchableOpacity>
</View>
You are passing the styles to the <TouchableOpacity> and the <Text> components. So they are both surrounded by the border
You pass style={styles.roomsbutton} to both the TouchableOpacity and the Text components. Each have a solid white border
this is happining because you apply className .roomsbutton two times in a button. once in TouchableOpacity and once in Text.
just remove style={styles.roomsbutton} form Text like below..
<Text>FIND MORE FREE ROOMS</Text>

React Native - Responsive image widths (percentages?)

I have a responsive photo grid built within a RN app -
I'd like 3 images to fit across the screen with the respective margin guttering. All images are squares.
I'm after some tips on the best way to achieve this - i'd use percentages in a web build for each image square but understand this isnt a possibility in RN..
This is what I have so Far:
The code basically pulls images out of an array via a map function and adds the grey image upload button at the same size after them as below:
<View style={PhotoStyles.imgThumbnailWrap}>
{this.state.ADImageArray.map((prop, key) => {
return (
<Image
source={{uri: prop, isStatic: true}}
style={PhotoStyles.imgThumbnail}
/>
);
})}
<TouchableOpacity onPress={this.photoAdditional} >
<View style={PhotoStyles.imgThumbAddMore}>
<Image source={require('../images/icons/ico-upload-
photo.png')} style={PhotoStyles.imgThumbnailBtn} />
</View>
</View>
Heres the Styles:
imgThumbnailWrap: {
flex:1,
flexDirection: 'row',
justifyContent: 'flex-start',
flexWrap:'wrap',
},
imgThumbnail: {
backgroundColor:'#f79431',
width:100,
height:100,
margin:8,
},
imgThumbAddMore: {
width:100,
height:100,
margin:8,
backgroundColor: '#e9e9e9',
alignItems:'center',
justifyContent: 'center',
},
As you can see the two image classes (imgThumbnail and imgThumbAddMore) have fixed widths in the above example - i'd like to make them fit in a row of 3 width percentage widths and height based on the width of the parent container (imgThumbnailWrap). Any advice?
You can divide the width of the device and subtract the margin on the outside
import { Dimensions } from "react-native";
const padding = 10
const itemWidth = (Dimensions.get('window').width / 3) - (padding * 4)
Use the itemWidth with both the width and height so you get perfect squares.
This problem can easily solve by using paddingTop, width, and position. Just try the below code.
<View style={{width:'100%',paddingTop:'100%'}}>
<Image source={{uri:url}} style={{position:'absolute',left:0,bottom:0,right:0,top:0,resizeMode:'contain'}} />
</View>
