oh_my_flutter

Small, strongly typed utilities for common Flutter application tasks.

Installation

Add the latest compatible release from pub.dev:

flutter pub add oh_my_flutter

Or add it directly to your pubspec.yaml:

dependencies:
  oh_my_flutter: ^0.11.0

Import the public library wherever you need it:

import 'package:oh_my_flutter/oh_my_flutter.dart';

Documentation

Read the repository consumer guides for setup, usage, configuration, and constraints.
Read the generated API reference for exhaustive contracts and defaults.
Run the complete public-API example.

Quick start

Extensions make common transformations concise while preserving Flutter and Dart types:

import 'package:flutter/material.dart';
import 'package:oh_my_flutter/oh_my_flutter.dart';

final accent = const Color(0xFFFF4A4B);
final lighterAccent = accent.lighten(0.12);
final hex = lighterAccent.toHex();
final oklch = lighterAccent.toOklch();

Extensions

DateTime relative time

DateTime.timeAgo maps elapsed time to application-owned callbacks, so callers control localization and the result type.

Color transformations

ColorExtension lightens, darkens, converts Flutter colors to hexadecimal, and starts OKLCH conversion.

OKLCH colors

Oklch provides perceptually uniform lightness, chroma, and hue values with conversion to and from Flutter colors.

Velocity classification

VelocityExtension classifies directional swipe velocity while leaving distance, progress, and interaction policy to the application.

Widgets

ControlledVisibility

ControlledVisibility lets parent-owned state show or hide a child with optional directional transitions and optional unmounting.

Morph

Morph animates matching widgets between layouts and routes, selecting a specialized transition for supported content and a generic transition for other widgets. MorphDescendant configures how a selected descendant subtree participates in its nearest ancestor Morph, currently including live, snapshotted, or hidden transition behavior. Discrete content switches and moving destinations remain configurable without replacing the automatic transition. MorphForeground keeps live controls visible above those flights without animating them as matched content.

Motion

Motion applies reusable one-shot or looping effects, including shakes, to any widget with configurable startup and controller-driven playback.

TextMotion

TextMotion applies the same motion effects to each visible grapheme in short display text with configurable startup and controller-driven playback.

Marquee

Marquee repeatedly moves an ordered strip through a clipped viewport, with gapless or single-strip cycle layouts.

PauseAnimations

PauseAnimations temporarily mutes ticker callbacks for a widget subtree.

MaybeSafeArea

MaybeSafeArea keeps a child's layout bounds out of enabled unsafe view edges as it moves or scrolls, without changing its layout footprint.

Sequence

Sequence presents one child at a time with controller-owned navigation and optional directional transitions.

RouteSettled

RouteSettled shows route chrome or controls only while the enclosing route is settled and no navigator gesture is active.

Networking

Offline Dio errors

OfflineErrorDioInterceptor turns conservatively classified offline Dio failures into a typed error that callers can detect without repeating connectivity probes.

Utilities

Device location

DeviceLocation manages foreground location permission and retrieves fresh coordinates on Android or iOS.

Telephony

Telephony sanitizes an international phone number and asks the platform to start a call.

Whatsapp opens a chat with an optional message through the native application or web fallback.

Scope

oh_my_flutter provides portable utility APIs. It intentionally does not own application state, routing, localization, design components, or application-specific domain logic.
