field_initialized_by_multiple_initializers

The field '{0}' can't be initialized twice in the same constructor.

The analyzer produces this diagnostic when the initializer list of a constructor initializes a field more than once. There is no value to allow both initializers because only the last value is preserved.

The following code produces this diagnostic because the field f is being initialized twice:

class C {
  int f;

  C() : f = 0, f = 1;
}

Remove one of the initializers:

class C {
  int f;

  C() : f = 0;
}
