Question

Is there any way to change the status bar color via Flutter Web in an installed PWA?

Answer 1

You want to change the value for theme-color. The default color is defined in your web/manifest.json file.

You could also set it, for example to white for your light-theme and to black for your dark-theme, by adding following lines to your web/index.html:

<meta name="theme-color" media="(prefers-color-scheme: light)" content="#FFFFFF">
<meta name="theme-color" media="(prefers-color-scheme: dark)"  content="#000000">

You could also change it dynamically via dart:js by adding a script to your web/index.html:

<script>
  function setMetaThemeColor(color) {
      document.querySelector('meta[name="theme-color"]').setAttribute("content", color);
    }
</script>

Then call it via dart:js:

import 'package:flutter/material.dart';
import 'dart:js' as js;

extension ColorString on Color {
  String toHexString() {
    return '#${(value & 0xFFFFFF).toRadixString(16).padLeft(6, '0').toUpperCase()}';
  }
}

void setMetaThemeColor(Color color) {
  js.context.callMethod("setMetaThemeColor", [color.toHexString()]);
}
