Are there any alternatives to adjustsFontSizeToFit for Android?

Question

I am using flex in Text field to display my values/range. For IOS I am using the properties adjustsFontSizeToFit and minimumFontScale props for Text to achieve the ideal font size and scaling. I want the same scaling to be enabled for Android. Does anyone use any tricks for Android?

<View style={{flex: 40}}>
  {
   (Platform.OS === 'ios') ?
    <Text style={{flex: 1, paddingRight: 2}} adjustsFontSizeToFit 
    minimumFontScale={0.5}>
     //if decimal value exists show range
     (pointFivePart_1 === '5') ? 
        <Text style={{ flexDirection: 'row' }} >
          <Text style={styles.mainValueStyle}>{first_1}</Text>
          <Text style=styles.decimalValueStyle}> .pointFivePart_1}</Text>
          <Text style={styles.mainValueStyle}>&deg;</Text>
         </Text>
         : <Text style={styles.mainValueStyle} >{min}&deg;</Text>
        }
        //if two values then show the second value as range
{// render largest value if different than min
            (maxSet === minSet) ? null : (
                (pointFivePart_2 === '5') ?
                <Text style={{ flexDirection: 'row' }} >
                    <Text style={styles.mainValueStyle}> - {first_2}</Text>
                    <Text style={styles.decimalValueStyle}>.{pointFivePart_2}</Text>
                    <Text style={styles.mainValueStyle}>&deg;</Text>
                    </Text>
                :
                    <Text style={styles.mainValueStyle} > - {maxSet}&deg;</Text>
                    )
                }
                </Text>
                :
                //same styling for android

Answer 1

Simply set adjustFontSizeToFit and numberOfLines DONT SET fontSize

<Text adjustsFontSizeToFit numberOfLines={1}>This text will fit the width of the container</Text>

Answer 2

Simple but somehow working solution (crossplatform):

fontSize = Math.sqrt(textWidth*textHeight/text.length)

where textWidth, textHeight - size of your Text component, text.length - length of your text.

minimumFontScale can be achieved with

fontSize = Math.max(fontSize,minimumFontSize)

I came to this formula by solving such system of equations:

lettersInLine = textWidth/fontSize
lines = textLength/lettersInLine
lines*fontSize = textHeight

assuming here that font has square sized (width equal to height) letters.

Though this formula makes sense even without equations. You just

1. calculate square of whole text element
2. calculate square for each letter (dividing whole square to letters number)
3. take square root from letter square to get font size
