How to Change Color of the Back Arrow in the New Material Theme

How to change color of the back arrow in the new material theme?

You can achieve it through code. Obtain the back arrow drawable, modify its color with a filter, and set it as back button.

final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(getResources().getColor(R.color.grey), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);

Revision 1:

Starting from API 23 (Marshmallow) the drawable resource abc_ic_ab_back_mtrl_am_alpha is changed to abc_ic_ab_back_material.

EDIT:

You can use this code to achieve the results you want:

toolbar.getNavigationIcon().setColorFilter(getResources().getColor(R.color.blue_gray_15), PorterDuff.Mode.SRC_ATOP);

Change toolbar back arrow color

You can override the theme in your Toolbar.

With a Material Components theme:

  <com.google.android.material.appbar.MaterialToolbar
        style="@style/Widget.MaterialComponents.Toolbar.Primary"
        android:theme="@style/MyThemeOverlay_Toolbar"
        ..>

with:

  <style name="MyThemeOverlay_Toolbar2" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">

    <!-- This attributes is used by navigation icon and overflow icon -->
    <item name="colorOnPrimary">@color/secondaryColor</item>
  </style>

With an AppCompat theme:

<android.support.v7.widget.Toolbar
  android:theme="@style/myToolbarTheme" 
  ...
>

Then in your theme you can define the colorControlNormal attribute:

   <style name=""  parent="ThemeOverlay.AppCompat.Dark.ActionBar">
      ....
      <item name="colorControlNormal">@color/myColor</item>  
   </style>

How to change the appBar back button color

You have to use the iconTheme property from the AppBar , like this:

appBar: AppBar(
  iconTheme: IconThemeData(
    color: Colors.black, //change your color here
  ),
  title: Text("Sample"),
  centerTitle: true,
),

Or if you want to handle the back button by yourself.

appBar: AppBar(
  leading: IconButton(
    icon: Icon(Icons.arrow_back, color: Colors.black),
    onPressed: () => Navigator.of(context).pop(),
  ), 
  title: Text("Sample"),
  centerTitle: true,
),

Even better, only if you want to change the color of the back button.

appBar: AppBar(
  leading: BackButton(
     color: Colors.black
   ), 
  title: Text("Sample"),
  centerTitle: true,
),

        <item name="colorControlNormal">@color/WhiteColor</item>
    </style>

and then use it in app:theme="@style/ToolbarTheme" in your Toolbar XML :

 <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_menu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#000000"
        android:textColor="#FFF"
        android:textColorPrimary="#FFF"
        app:theme="@style/ToolbarTheme"
