drift

Package drift provides the main entry point for Drift applications.

func Dispatch

func Dispatch(callback func())

Dispatch schedules a callback to run on the UI thread during the next frame and is safe to call from any goroutine.

Example:

This example shows how to dispatch work to the UI thread from a background goroutine. Use Dispatch when you need to update UI state from async operations like network calls.

package main

import (
	"github.com/go-drift/drift/pkg/drift"
)

func main() {
	// Simulating an async operation that needs to update UI
	go func() {
		// ... do some work in the background ...

		// Schedule UI update on the main thread
		drift.Dispatch(func() {
			// This code runs on the UI thread and can safely update state
			// state.SetState(func() {
			//     state.data = result
			// })
		})
	}()
}

func Run

func Run(app App)

Run initializes the Drift engine with the given App configuration.

type App

App defines the configuration for a Drift application.

type App struct {
    // Root is the root widget of the application.
    Root core.Widget
    // Theme is the application theme. Defaults to DefaultLightTheme if nil.
    Theme *theme.ThemeData
    // DeviceScale is the device pixel ratio. Defaults to 1.0 if zero.
    DeviceScale float64
}

Example (With Theme):

This example shows how to create an app with a custom theme.

package main

import (
	"github.com/go-drift/drift/pkg/drift"
	"github.com/go-drift/drift/pkg/theme"
	"github.com/go-drift/drift/pkg/widgets"
)

func main() {
	root := widgets.Center{
		ChildWidget: widgets.Text{Content: "Dark Mode App"},
	}

	app := drift.App{
		Root:        root,
		Theme:       theme.DefaultDarkTheme(),
		DeviceScale: 2.0, // For high-DPI displays
	}
	_ = app
}

func NewApp

func NewApp(root core.Widget) App

NewApp creates a default App with the given root widget.

Example:

This example shows how to create and configure a Drift application.

package main

import (
	"github.com/go-drift/drift/pkg/drift"
	"github.com/go-drift/drift/pkg/widgets"
)

func main() {
	// Create the root widget for the application
	root := widgets.Center{
		ChildWidget: widgets.Text{Content: "Hello, Drift!"},
	}

	// Create an app with default settings
	app := drift.NewApp(root)
	_ = app
}

func (App) Run

func (app App) Run()

Run starts the app using the package-level runtime.
