# navigator

![build](https://github.com/KaustubhPatange/navigator/workflows/build/badge.svg)

> **Looking for Jetpack Compose implementation of `navigator`, see [here](navigator-compose)**.

A small (Kotlin first) type-safe navigation library for Android to ease the use of fragment transactions with a `navigator.navigateTo`
call (rest is handled for you) & navigating back is as simple as `navigator.goBack()`.

You also get a separate `onBackPressed()` callback on the child fragments which will be called when `this` is the current visible fragment & is the one which is going to be removed upon back press.

The library provides some custom transitions like `CircularTransform` (on top of existing animations), see its
use in the sample app [here](/samples/backpress-sample).

If you have any implementation details to cover let me know.

**What additional benefits I can get when using this library?**

- Proper handling of Fragment Transaction.
- Handling up & back press actions efficiently on [Fragment](/samples/basic-sample).
- Easy to use API for animations & transitions (see [here](https://github.com/KaustubhPatange/navigator/wiki/Quick-Tutorials#navigation-with-animation)).
- Generic Typed Arguments when passing data between destinations (see [here](https://github.com/KaustubhPatange/navigator/wiki/Quick-Tutorials#navigation-with-typed-arguments)).
- Quick Bottom & Tab navigation setup (see [tutorials](#tutorials)).

## Implementation

![Maven Central](https://img.shields.io/maven-central/v/io.github.kaustubhpatange/navigator)

```groovy
// root's build.gradle
allprojects {
    repositories {
        mavenCentral()
    }
}
```

```groovy
// modules's build.gradle
dependencies {
    implementation "io.github.kaustubhpatange:navigator:<version>" // Core library (Required)
    implementation "io.github.kaustubhpatange:navigator-extensions:<version>" // Optional but recommended
    implementation "io.github.kaustubhpatange:navigator-bottom-navigation:<version>" // For setting up Bottom Navigation.
    implementation "io.github.kaustubhpatange:navigator-tab-navigation:<version>" // For setting up Tab Layout Navigation.
    implementation "io.github.kaustubhpatange:navigator-rail-navigation:<version>" // For setting up Rail Navigation.
}
```
