Custom Toast For Android

Create a file named toast_custom.xml in your project app/res/layout folder and do custom styling

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginStart="50dp"
    android:background="@drawable/corner"
    android:layout_marginEnd="50dp">

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#CC000000"
        android:paddingStart="16dp"
        android:paddingTop="10dp"
        android:paddingEnd="16dp"
        android:paddingBottom="10dp"
        android:textStyle="bold"
        android:textColor="#FFFFFF"
        tools:text="Toast should be short." />
</FrameLayout>

Toast with BuildContext (All Platforms)

Update your MaterialApp with builder like below for the use of Context globally check doc section Use NavigatorKey for Context(to access context globally)

MaterialApp(
    builder: FToastBuilder(),
    home: MyApp(),
    navigatorKey: navigatorKey,
),

FToast fToast;

@override
void initState() {
    super.initState();
    fToast = FToast();
    // if you want to use context from globally instead of content we need to pass navigatorKey.currentContext!
    fToast.init(context);
}

_showToast() {
    Widget toast = Container(
        padding: const EdgeInsets.symmetric(horizontal: 24.0, vertical: 12.0),
        decoration: BoxDecoration(
        borderRadius: BorderRadius.circular(25.0),
        color: Colors.greenAccent,
        ),
        child: Row(
        mainAxisSize: MainAxisSize.min,
        children: [
            Icon(Icons.check),
            SizedBox(
            width: 12.0,
            ),
            Text("This is a Custom Toast"),
        ],
        ),
    );


    fToast.showToast(
        child: toast,
        gravity: ToastGravity.BOTTOM,
        toastDuration: Duration(seconds: 2),
    );
    
    // Custom Toast Position
    fToast.showToast(
        child: toast,
        toastDuration: Duration(seconds: 2),
        positionedToastBuilder: (context, child) {
          return Positioned(
            child: child,
            top: 16.0,
            left: 16.0,
          );
        });
}

Now Call _showToast()

For more details check example project

property	description	default
child	Widget (Not Null)(required)	required
toastDuration	Duration (optional)
gravity	ToastGravity.*

Use NavigatorKey for Context(to access context globally)

To use NavigatorKey for Context first define the GlobalKey<NavigatorState> at top level in your main.dart file

GlobalKey<NavigatorState> navigatorKey = GlobalKey<NavigatorState>();

At the time of initializing the FToast we need to use context from globally defined GlobalKey<NavigatorState>

FToast fToast = FToast();
fToast.init(yourNavKey.currentContext!);

To cancel all the toasts call

// To remove present shwoing toast
fToast.removeCustomToast()

// To clear the queue
fToast.removeQueuedCustomToasts();
