ByteConverter #

Fast, dependable byte and data-rate conversions for Dart with fluent APIs and optional BigInt precision.

✨ Highlights #

• 🚀 Instant parsing and formatting for bytes, bits, and rates across SI, IEC, and JEDEC standards
• 🧮 Expression-friendly math with operators, durations, and auto unit detection
• 🧠 BigInt precision via BigByteConverter plus matching DataRate and BigDataRate APIs
• 🕒 Transfer planning helpers that surface ETAs, progress, and burst windows in a single call
• 📦 Storage profiles with configurable alignment, slack inspection, and round-to-profile helpers
• 📊 Aggregate metrics through ByteStats/BigByteStats for sums, averages, percentiles, and histograms
• 🌍 Localization-ready humanize output with custom format options, optional intl integration, and built-in unit names for English (including en_IN), German, French, Hindi, Spanish, Portuguese, Japanese, Chinese, and Russian
• ✍️ Formatting ergonomics: fixed-width numeric alignment (fixedWidth), sign-aware padding (includeSignInWidth), non‑breaking space (nonBreakingSpace), truncation (truncate), SI k‑case styling (KB vs kB), and pattern formatting with tokens u/U/S
• 🧰 CLI goodies: --pattern, --per for rate time base, --fixed-width, --si-lower-k, --nbsp, --truncate, and --strict-bits
• 🧾 FormatterSnapshot generators that keep README/wiki matrices and snapshot tests in sync

📦 Installation #

dependencies:
  byte_converter: ^2.4.0

💡 Quick Example #

import 'package:byte_converter/byte_converter.dart';

void main() {
  final size = ByteConverter.parse('2.5 GB');
  final rate = DataRate.parse('150 Mbps');
  final plan = size.estimateTransfer(rate);

  print(size.toHumanReadableAuto()); // 2.5 GB
  print(plan.etaString());           // friendly ETA string
}

🛠️ Common Tasks #

// Expression-aware parsing and humanizing
final payload = ByteConverter.parse('(1 GiB + 512 MiB) - 256 MB');
print(payload.toHumanReadableAuto());

// Transfer windows and alignment checks
final burst = DataRate.parse('500 Mbps').transferableBytes(const Duration(seconds: 10));
final aligned = burst.roundToProfile(
  StorageProfile.singleBlock('object', blockSizeBytes: 4 * 1024 * 1024),
);

// Aggregations across mixed inputs
final total = ByteStats.sum([
  payload,
  burst,
  ByteConverter.parse('750 MB'),
]);
print(total.toHumanReadableAuto());

🔌 Optional Add-ons #

• byte_converter_intl.dart opt-in delivers locale-aware number formatting and localized unit names

• Built-in localized vocabulary now spans English (including en_IN), German, French, Hindi (hi/hi_IN), Spanish (es), Portuguese (pt), Japanese (ja), Chinese (zh), and Russian (ru)

• FormatterSnapshot helpers keep README tables, wiki docs, and snapshot tests aligned

• Wiki recipes cover CLI usage, monitoring dashboards, and BigInt-heavy workloads

• byte_converter_lite.dart opt-in provides lightweight locale-aware number formatting (no intl dependency) for common locales. See wiki: Formatting – Lightweight number formatter.

🧠 Advanced capabilities #

We also support advanced features—see the wiki for details and examples:

• Transfer planning with schedules, throttle, and pause/resume
• Locale-aware parsing (parseLocalized) and tree-shakable unit name maps
• OS parsing adapters (Linux ls -lh, Windows short sizes)
• Streaming quantiles (P²) for p50/p95/p99
