Convert double to int

To convert a double to int in Dart, we can use one of the built-in methods depending on your need:

toInt( ) or truncate( ): these 2 methods are equivalent, they both truncate the fractional/decimal part and return the integer part.

round( ): return the closest/nearest integer.

ceil( ): return the least integer that is not smaller than this number.

floor( ): return the greatest integer not greater than this number.

void main() {
  double d = 10.3;

  print(d.toInt());     // 10
  print(d.truncate());  // 10
  print(d.round());     // 10
  print(d.ceil());      // 11
  print(d.floor());     // 10
}

Convert int to double

So far, I know 2 ways to convert an integer to a double in Dart:

toDouble( )

: as its name is saying, just convert the integer to a double

double.tryParse( )

: provide an integer as a String to this method

void main() {
  int i = 5;
  print(i.toDouble());          // 5.0
  print(double.tryParse('$i')); // 5.0
}

How to convert List to int type in flutter

Just parse your data with int.parse(//your data)

var data=”18:00″;
List dataList = data.split(‘:’);
print(int.parse(dataList[0]));
print(int.parse(dataList[1]));

Dart convert int variable to string

Use toString and/or toRadixString

int intValue = 1;
  String stringValue = intValue.toString();
  String hexValue = intValue.toRadixString(16);

or, as in the commment

 String anotherValue = 'the value is $intValue';

String to int

String s = "45";
int i = int.parse(s);

int to String

int j = 45;
String t = "$j";

You can use the .toString() function in the int class.

int age = 23;
String tempAge = age.toString();
