This tutorial shows how to to convert radian to degree and vice versa in Dart which also works in Flutter.
Below is the equation for conversion between those two measurement units.
which can be written as
1° = π/180°
1° equals to 0.0174533 radians, while 1 radians equals to 57.2958°
Even though Dart doesn't provide the methods for converting between radian and degree out of the box, there are packages providing methods for that purpose if you don't want to create your own method.
Converting Radian to Degree & Vice Versa Using
vector_math is a library from Google Developers that provides the functionality to do the conversions.
First, you need to add the following dependency to the
dependencies section of your
dependencies: vector_math: any
Then you need to import the library on the file you want to invoke the methods.
Converting Radian to Degree
For converting radian to degree, use
degrees(0); // 0.0 degrees(1); // 57.29577951308232
Converting Degree to Radian
For converting degree to radian, use
radians(0); // 0.0 radians(57.29577951308232); // 1.0 radians(90); // 1.5707963267948966 radians(360); // 6.283185307179586xx
That's how to perform conversion between those two measurement units.
