Answer 1

You can use the NumberFormat class of flutter which has some in built functions for results you want..

Check out this link for NumberFormat class of flutter

Example: This is one way if you want to use currency..

var _formattedNumber = NumberFormat.compactCurrency(
  decimalDigits: 2,
  symbol: '', // if you want to add currency symbol then pass that in this else leave it empty.
).format(numberToFormat);

print('Formatted Number is: $_formattedNumber');

Example: This example is with locale.

var _formattedNumber = NumberFormat.compactCurrency(
  decimalDigits: 2,
  locale: 'en_IN'
  symbol: '',
).format(numberToFormat);

print('Formatted Number is: $_formattedNumber');

The output of this is code would be:

If 1000 is entered then 1K is the output

Another way is by just using NumberFormat.compact() which gives the desired output...

// In this you won't have to worry about the symbol of the currency.
var _formattedNumber = NumberFormat.compact().format(numberToFormat);
print('Formatted Number is: $_formattedNumber');

The output of above example will also be:

If 1000 is entered then 1K is the output

I tried this and is working...
