I am not able to access 'this' keyword in my static method in react- native, when I try to access it, it's thrown me error like 'this.setState not a function'.
Here is my code.
static getShiftStatus = () =>{
//for check shift start or not
Usermodal.getShiftStatus((isStatus) =>{
this.setState({isShiftStart: isStatus}) //error occure here.
console.log(a.state.isShiftStart)
})
}

Static methods aren't called on instances of the class, so if you just remove thestatickeyword it should work as expected.

Bind the method to the instance in the constructor?

this in the inner function points to something else.
You need to capture the this from the outside function.
static getShiftStatus = () =>{
var that = this; // capture here
Usermodal.getShiftStatus((isStatus) =>{
that.setState({isShiftStart: isStatus}) // use it here
console.log(a.state.isShiftStart)
})
}

But the inner function is an arrow function, so doesn't it use thethisvalue from its containing context?
