# validable

![Maven Central Version](https://img.shields.io/maven-central/v/tech.devscast/validable?color=blue)

[![build](https://github.com/devscast/validable/actions/workflows/build.yaml/badge.svg)](https://github.com/devscast/validable/actions/workflows/build.yaml)

Validable is an extensible library that simplifies text field validation for Jetpack Compose by providing abstraction and reusable validation logic.

This is what it looks like :



```kotlin  

@Composable  

fun MyScreen() { 

 

     val emailField = remember { EmailValidable() }

    // pass all fields to the withValidable method

    val validator = rememberValidator(emailField)

    TextField(  

	    value = emailField.value,

	    onValueChange = { emailField.value = it }, // update the text  

	    isError = emailField.hasError(), // check if the field is not valid    

	)  

  

	AnimatedVisibility(visible = emailField.hasError()) {

	

	    Text(

                text = emailField.errorMessage ?: "",

            	modifier = Modifier.fillMaxWidth(),

            	style = LocalTextStyle.current.copy(color = MaterialTheme.colors.error)

	    )

        

	}  

	

	Button(

        // a state to check if all fields are valid, without submitting the form

        enabled = validator.isValid,

        onClick = { 

            validator.validate { 

                // will be executed if all fields are valid 

                Toast.makeText(context, "All fields are valid", Toast.LENGTH_SHORT).show()

            } 

        }

    ) { 

		Text(text = "Submit") 

	}  

}  

```
